Nankai Tracts in Mathematics - Vol. 5 CONTEMPORARY TRENDS IN ALGEBRAIC GEOMETRY AND ALGEBRAIC TOPOLOGY edited by Shiing-Shen Chern, Lei Fu (Nankai Institute of Mathematics, P R China) (Duke University, USA) About the Editors Professor S S Chern retired from UC Berkeley and is now based in the Nankai Institute of Mathematics, which he founded in 1985. He is also the founding director of the Mathematical Science Research Institute, Berkeley (1981). He was awarded the National Science Medal in 1975 and Wolf Prize in Mathematics in 1983/4. His area of research was differential geometry where he studied the (now named) Chern characteristic classes in fibre spaces. The Chern Visiting Professorship, begun in 1996, honors the Berkeley professor emeritus widely regarded as the greatest geometer of his generation. "Chern's belief in young people and his encouragement of them had a lot to do with the spectacular growth of geometry in the second half of this century" mathematician Blaine Lawson has said. "It is not easy to find a geometer who was not for some period of time either a student or a post-doctoral fellow in the orbit of Chern. (http://math.berkeley.edu/) Professor Chern is also the editor of the book – Selected Papers of Wei-Liang Chow, also published by World Scientific Publishing.

Algebraic Topology, An Introduction Search Site map Contact us Main Page X Algebraic Topology Covering Spaces Use the arrows at the bottom to step through Algebraic Topology. Introduction As the name suggests, algebraic topology is a marriage of algebra and topology. These branches of mathematics seem unrelated, yet they can be connected in several ways. For instance, a topological space s might be assigned a group g, based on the propertyies of s, in such a way that any space homeomorphic to s will be given the same group g. Therefore, two spaces that exhibit different groups cannot be homeomorphic. Proving a negative is always difficult; this is often the only way we can prove two spaces are different from each other. Consider a simple example, the line and the plane. These spaces seem different enough, yet they have the same cardinality. There are invertable functions that map the plane onto the line and back again. Perhaps one of these functions preserves open sets. Perhaps one dimension is really the same as two, when viewed from the right perspective. This isn't true of course; the plane is different from the line. But we need algebraic topology to prove it. The groups associated with these spaces (actually their compactifications) are different, and that closes the case.

One such example is given by the deformation theorem for contour integrals of a holomorphic function. The main idea in algebraic topology is to associate algebraic objects such as groups and rings to a space, which reflect its geometry up to these deformations. This allows algebraic topologists to prove statements such as ``one cannot comb a ball". While problems like this have been important for the development of the subject and illustrate its power, the ideas and techniques of homological algebra have by now entered into nearly every branch of mathematics. The algebraic invariant underlying the deformation theorem is the fundamental group, and this will be studied first. The second part of the course will introduce homology groups which will catch higher dimensional properties of the space. Tools like the Mayer-Vietoris sequence will help to compute the homology groups of a large number of spaces. 1.3.3.2 Synopsis

A User's Guide to Algebraic Topology C.T.J. Dodson Department of Mathematics, University of Manchester Institute of Science and Technology, Manchester, M60 1QD UK Phillip E. Parker Department of Mathematics, Wichita State University, KS 67260-0033, USA Mathematics and Its Applications Volume 387, Kluwer Academic Publications, Dordrecht 1997, 1998 This book arose from courses taught by the authors, and is designed for both instructional and reference use during and after a first course in algebraic topology. It is a handbook for users who want to calculate, but whose main interests are in applications using the current literature, rather than in developing the theory. Typical areas of applications are differential geometry and theoretical physics. We start gently, with numerous pictures to illustrate the fundamental ideas and constructions in homotopy theory that are needed in later chapters. We show how to calculate homotopy groups, homology groups and cohomology rings of most of the major theories, exact homotopy sequences of fibrations, some important spectral sequences, and all the obstructions that we can compute from these. Our approach is to mix illustrative examples with those proofs that actually develop transferable calculational aids. We give extensive appendices with notes on background material, extensive tables of data, and a thorough index. Audience: Graduate students and professionals in mathematics and physics.

General Description of the Unit We begin by discussing relevant topics in general topology. These include compactness, path-connected spaces, Hausdorff spaces, convex spaces and the compact-Hausdorff lemma. We define homotopy between continuous functions, contractibility, homotopic spaces. We calculate the fundamental group of the circle and use this to prove the Fundamental Theorem of Algebra. We introduce simplicial complexes in order to provide a more general method for calculating the fundamental group. In order to prove this method works we need the Simplicial Approximation Theorem. We introduce homology and again use the simplicial approximation theorem to show how to calculate this for simplicial complexes. In the section on homology, the geometric methods are in the main sketched whilst the algebraic results have rigorous proofs.

Algebraic Topology What is Algebraic Topology? THE BEGINNINGS OF ALGEBRAIC TOPOLOGY The winding number of a curve illustrates two important principles of algebraic topology. First, it assigns to a geometric odject, the closed curve, a discrete invariant, the winding number which is an integer. Second, when we deform the geometric object, the winding number does not change, hence, it is called an invariant of deformation or, synomynously, an invariant of homotopy. THE TWENTIETH CENTURY VIEWPOINT Modern algebraic topology is the study of the global properties of spaces by means of algebra. Poincaré was the first to link the study of spaces to the study of algebra by means of his fundamental group. This is a generalization of the concept of winding number which applies to any space. The concept of continuous deformation can be illustrated by the following examples. Consider a coffee cup (with a handle) and a donut. If they are both made of some pliable substance like modeling clay, they can be deformed continuously (without ripping them apart into pieces) one into the other. This means that they have the same homotopy and homology groups, that is, the homotopy groups and the homology groups are invariant. On the other hand, a donut cannot be continuously deformed into a sphere. This means that their homotopy and homology groups can be different and they are.

On A-branes with Real Dimension 5 Takao Akahori Department of Mathematics School of Science, University of Hyogo Himeji, Hyogo akahorit@sci.u-hyogo.ac.jp Abstract : Let W be an open Kaehler manifold and let w W be its Kaehler form. Let M be a coisotropic submanifold of W with a line bundle and a connection. Kapustin-Orlov formulate when this coisotropic submanifold admits an A-brane (see [Kap-Or]). Let L be the characteristic foliation of M. And let F TM L Then, M admits an A-brane iff [1] The curvature of the connection, F , is an element of G (M, F [2] J: = w W F determines a "Tac" structure on M(this means that:J = -1 and this J is integrable modulo characteristic foliation ). The condition [2] reminds us of the hyperKaehler structure over a minimal resolution of the rational double point. Namely, let W be a minimal resolution of the rational double point, and let M = W(in this case, no characterstic foliation). Then, by Kronheimer's work(see [Kro]), there are integrable complex structures I,J,K, and associated Kaehler forms. And so, this minimal resolution adimts an A-brane. While, we assume that there is a 1-dimensional foliation and the dimension of F is a real 4-dimenional(a real hypersurface in a complex 3-dimensional manifold). Even though our CR structure is 2-dimensional, complex 2-dimensional analogue completely breaks down. However, it seems natural to try to obtain some analogue(some CR structures should admit A-branes). In this paper, we discuss the real hypersurface M in a complex 4-dimensional euclidaen space, defined by:
