Algebraic Topology: An Introduction by William S. Massey

By William S. Massey

Ocr'd

William S. Massey Professor Massey, born in Illinois in 1920, got his bachelor's measure from the collage of Chicago after which served for 4 years within the U.S. army in the course of global warfare II. After the battle he obtained his Ph.D. from Princeton collage and spent extra years there as a post-doctoral study assistant. He then taught for ten years at the school of Brown collage, and moved to his current place at Yale in 1960. he's the writer of various study articles on algebraic topology and similar themes. This publication built from lecture notes of classes taught to Yale undergraduate and graduate scholars over a interval of a number of years.

Topology and analysis: The Atiyah-Singer index formula and gauge-theoretic physics

The Atiyah-Singer Index formulation is a deep and demanding results of arithmetic that's recognized for its trouble in addition to for its applicability to a few likely disparate topics. This e-book is the 1st try and render this paintings extra obtainable to newcomers within the box. It starts off with the examine of the neccessary themes in practical research and research on manifolds, and is as self-contained as attainable.

Elements of Homology Theory

The publication is a continuation of the former e-book via the writer (Elements of Combinatorial and Differential Topology, Graduate experiences in arithmetic, quantity seventy four, American Mathematical Society, 2006). It begins with the definition of simplicial homology and cohomology, with many examples and purposes.

Topology Optimization: Theory, Methods, and Applications

The topology optimization procedure solves the elemental engineering challenge of dispensing a constrained quantity of fabric in a layout house. the 1st variation of this booklet has turn into the traditional textual content on optimum layout that is interested in the optimization of structural topology, form and fabric. This variation has been considerably revised and up-to-date to mirror growth made in modelling and computational strategies.

Molecules Without Chemical Bonds

In fresh technical literature a growing number of of frequently one comes throughout such phrases as "topology of a molecule", " topological properties", "topological bonding", and so on. by and large, topology is a department of arithmetic facing the phenomenon of continuity. A extra distinct definition will require from the reader a extra profound wisdom of many advanced mathematical techniques.

Example text

The fact that the set of all the triangles with v as a vertex can be divided into several disjoint subsets, such that the triangles in each subset can be arranged in cyclic order as described, is an easy consequence of condition (1). However, if there were more than one such subset, then the requirement that 22 have a neighborhood homeomorphic to U2 would be violated. We shall not attempt a rigorous proof of this last assertion. 1 Let S be a compact surface. 1 by prov- ing that S is homeomorphic to a polygon with the edges identified in pairs as indicated by one of the symbols listed at the end of Section 5.

We identify the edges a and b with two edges of the triangulation of the boundary of M, and count vertices, edges, and triangles before and after the identification. Now, we shall show how to construct any compact, orientable bordered surface whose boundary has 15 components, 15 g 1. 34 for k = 4. An orientable bordered surface of Euler characteristic 2 — 15 whose boundary has 15 components results. Note that the Euler characteristic is the maximum possible for the given number of boundary components.

We can state this in another way: If we start with a compact surface M * and construct a bordered surface by removing the interiors of k closed discs, which are pairwise disjoint, then the location of the discs that are to be removed does not matter. The resulting manifold with boundary will be topologically the same no matter how the position of the discs is chosen. 1 Let M1 and M2 be compact bordered surfaces; assume that their boundaries have the same number of components. Then, M1 and M 2 are homeomorphic if and only if the surfaces M1" and M;* (obtained by gluing a disc to each boundary component) are homeomorphic.
