Light Detectors, Photoreceptors, and Imaging Systems in Nature
Jerome J. Wolken Manufacturer: Oxford University Press, USA ProductGroup: Book Binding: Hardcover ASIN: 0195050029 |
Book Description
The influence of light on the lives of living organisms is all-pervasive, affecting movement, vision, behavior, and physiological activity. This book is a biophysically grounded comparative survey of how animals detect light and perceive their surroundings. Included are discussions of photoreceptors, light emitters, and eyes. The book focuses in particular on the kinds of optical systems that have evolved, beginning with unicellular organisms that detect and respond to light through to more advanced and complex designs for imaging. The relevance of these studies extends beyond biology, since these findings can be used to help develop photoreceptor energy conversion and information systems, and optical imaging devices with a wide range of everyday applications. The book will appeal to biophysicists, photobiologists, bioengineers, neuroscientists, and all researchers working in the area of vision and visual optics.

ASIN: 0387943706 |
Book Description
This book provides an introduction to the theory of quantum groups with emphasis on the spectacular connections with knot theory and on Drinfeld's recent fundamental contributions. The first part presents in detail the quantum groups attached to SL2 as well as the basic concepts of the theory of Hopf algebras. Part Two focuses on Hopf algebras that produce solutions of the Yang-Baxter equation, and on Drinfeld's quantum double construction. In the following part we construct isotopy invariants of knots and links in the three-dimensional Euclidean space, using the language of tensor categories. The last part is an account of Drinfeld's elegant treatment of the monodromy of the Knizhnik-Zamolodchikov equations, culminating in the construction of Kontsevich's universal knot invariant.Customer Reviews:
For quantum mathematicians.......2001-09-03
An in-depth reading of the book is time-consuming, and no doubt the average reader will not read it from cover to cover but instead will peruse only the areas of immediate interest. Part One of the book is an overview of what the author calls quantum SL(2), which is an example of a Hopf algebra. The first two chapters are purely a review of algebra, with the third being an introduction to coalgebras, which the author, in a categorical sense, identifies as being dual to an algebra. The notion of a bialgebra is also discussed, which is essentially a vector space equipped with both an algebra structure and a coalgebra structure. Taking a tensor product of this vector space with itself and examining certain morphisms between these structures gives a set of compatibility conditions that define the bialgebra structure. A Hopf algebra is then a bialgebra that has a special endomorphism of the underlying vector space. The algebraic topologist reader will be familiar with Hopf algebras via studies of product manifolds such as Lie groups. Quantum groups have given many examples of non-commutative non-cocommutative bialgebras than were known before this research area had taken off. The author also discusses the quantum plane as an object that generalizes the affine plane, namely the two variables x, y generating the plane no longer commute but instead satisfy yx = q xy. The author investigates in detail the quantum group SLq(n), which is based on the classical Lie group. References are given for quantum groups based on the other Lie groups, such as the orthogonal and symplectic groups. The Lie algebra Uq(sl(2)) is given a detailed treatment by the author when q is not a root of unity. This Hopf algebra is a 1-parameter deformation of the enveloping algebra of the Lie algebra sl(2) considered in earlier chapters. The reader interested in the renormalization is strongly urged to read this first part, as recently it has been shown that for any quantum field theory, the combinatorics of Feynman diagrams gives rise to a Hopf algebra which is commutative as an algebra, and is the dual Hopf algebra of the enveloping algebra of a Lie algebra whose basis is labelled by one particle irreducible Feynman diagrams. The Lie bracket of two diagrams is computed from insertions of one graph in the other and vice versa, and the Lie group G is the group of characters of the Hopf algebra. This structure is used to go on and formulate the renormalization problem rigorously.
Part two is an overview of the famous Yang-Baxter equation whose exact solutions in terms of R-matrices have generated a vast amount of research. The author introduces the concept of a braided bialgebra, which contain a "universal" R-matrix which induces a solution of the Yang-Baxter equation on all of their modules, and thus giving a systematic method for constructing solutions of the Yang-Baxter equation. The duals of these bialgebras give a cobraided bialgebra, and the author shows how to construct a cobraided bialgebra out of any solution of the Yang-Baxter equation. It is also shown how the quantum groups GLq(2) and SLq(2) can be obtained by this method, and it is proven that they are cobraided. The famous Drinfeld quantum double, yielding a braided Hopf algebra out of any finite-dimensional Hopf algebra with invertible antipode, is discussed in great detail.
The next part is basically low-dimensional topology in the form of knots, links, and braids, wherein the author discusses the relationship between the Jones polynomial and R-matrices. The connection between knot theory and quantum groups is given by the representation theory of Hopf algebras, this connection taking place in the tensor category. A certain strict tensor category is built out of tangles, and shown to give isotopy invariants of links. Braiding in the tensor category is used to formalize the notion of crossing in link and tangle diagrams. Tensor categories modeled on framed tangles or "ribbons" are introduced to illustrate duality. The concept of a quasi-bialgebra is introduced and braid group representations of these are constructed. When quasi-bialgebras are equivalent under a "gauge transformation" introduced here, they have the same braid group representation.
The last part considers the role of monodromy in the theory of quantum groups. The quantum enveloping algebras due to Drinfeld and Jimbo are discussed and shown to provide isotopy invariants of links. The monodromy of the Knizhnik-Zamolodchikov system is shown to be equivalent to the braid group representation of this system. Knot invariants of finite type are shown to be universal invariants for quantum groups.

Kac Algebras and Duality of Locally Compact Groups
Michel Enock , and Jean-Marie Schwartz Manufacturer: Springer ProductGroup: Book Binding: Hardcover ASIN: 3540547452 |
Book Description
The theory of Kac lagebras and their duality, elaborated independently in the seventies by Kac and Vainermann and by the authors of this book, has nowreached a state of maturity which justifies the publication of a comprehensive and authoritative account in bookform. Further, the topic of "quantum groups" has recently become very fashionable and attracted the attention of more and more mathematicians and theoretical physicists. However a good characterization of quantum groups among Hopf algebras in analogy to the characterization of Lie groups among locally compact groups is still missing. It is thus very valuable to develop the generaltheory as does this book, with emphasis on the analytical aspects of the subject instead of the purely algebraic ones. While in the Pontrjagin duality theory of locally compact abelian groups a perfect symmetry exists between a group and its dual, this is no longer true in the various duality theorems of Tannaka, Krein, Stinespring and others dealing with non-abelian locally compact groups. Kac (1961) and Takesaki (1972) formulated the objective of finding a good category of Hopf algebras, containing the category of locally compact groups and fulfilling a perfect duality. The category of Kac algebras developed in this book fully answers the original duality problem, while not yet sufficiently non-unimodular to include quantum groups. This self-contained account of thetheory will be of interest to all researchers working in quantum groups, particularly those interested in the approach by Lie groups and Lie algebras or by non-commutative geometry, and more generally also to those working in C* algebras or theoretical physics.

A depressingly overrated waste of paper.......2003-03-17
I think Beckett intended them to represent the mixture of boredom, madness, and detachment which is an essential part of most people's psyche (especially the thoughtful), but he does not achieve this goal in the least. There are a million books which express the desperation and hollowness of life, with a tinge of humor (and indeed there are a few moments of this book which are humorous, or at least attempts at humor). This is perhaps one of the most overrated of this sort of book.
Beckett's writing style is unique and, for the most part, good. My favorite line in this book came at the end of a lengthy descriptive paragraph: "End of descriptive passage." But the actual substance of this book does not live up to the promise provided by the style. While I tend to love the strange and the unique in art (especially books about people who seem at once hideously abornal and yet universal), "Mercier and Camier" proves that not all books about distinctively bizarre characters are good.
You'd be better off seeing "Waiting for Godot," or better yet, read something by Shakespeare.
Waiting for Poe.......2000-10-05
In "Mercier and Camier," the journey shapes the plot as the two men parade on an endless quest. Despite its somberness, it is in some ways a warm and funny book, occasionally tinged with stinging sarcasm. There are secondary characters, skillfully and swiftly delineated, so bizarre that even the two oddities of the title are struck by their madness. Mercier and Camier are otherworldly figures themselves, but they need the trappings of the real world in order to give their story coherence, and this is no doubt part of the reason why Beckett chose to abandon them and go on to the Malones and Malloys of his later fiction.
Just about this time, Beckett discovered that writing was for him the most intensely personal experience possible, depending not on verbal virtuosity or on the careful construction of the traditional novel. For him, creation satisfied only when he could plumb the depths of his unconscious, find an incident from his own life, and then work to conceal biography within the framework of his creative consciousness, changing dimensions of time and space according to the whim of his fictional voices. He reduces life to a series of tales, told first by one, then another (perhaps the same) voice, but all the voices are his.
Beckett perfected this method of writing novels when he discovered what he has called the most important revelation of his literary career--the first person monologue. He found he could create a multi-dimensional universe through the use of a voice telling a story. At the same time, this relentless voice could reveal character in its most desperate loneliness, stripping it as never before in contemporary fiction.
Written just before "Molloy," "Mercier and Camier" stands on the threshold of Beckett's mature fiction. There are large chunks of dialogue which he later transferred directly into Godot, but here speech is encumbered by a plot with progression and movement, albeit circuitous and often contradictory. There is a narrator, as in "Murphy" and "Watt," who occasionally intrudes to inject an acerbic comment and who thinks nothing of slowing down, speeding up, or otherwise circumventing the progress of the "pseudo-couple" (as they are called in "The Unnamable").
"Mercier and Camier" is about voluntary exile, much like Beckett's own. While it can be read as the odyssey of Beckett and the other young Irishmen who went to Paris in the 1930's hoping to gain the same success as their countryman of an older generation, James Joyce, it can also be read as two aspects of the personality of Beckett himself. Before his departure, he had been easily recognizable in Dublin by his shapeless, dirty raincoat, several sizes too large. He was plagued by recurring idiosyncratic cysts. When he wrecked his own car, he had continuous problems with his bicycle. In a drunken moment, he lost his favorite hat, which he mourned long afterwards.
It is the raincoat, however, which best symbolizes the final division of his first 30 years from the rest of his life, as well as this novel's place in his canon: when he left Dublin, Beckett threw his raincoat away, just as Mercier and Camier, after throwing theirs away, walk off into their own uncertain future, looking back now and again at the heap on the ground--unwilling to go on with it, but hesitant to abandon it...
