Prospects in topology: proceedings of a conference in honor of William Browder

This assortment brings jointly influential papers via mathematicians exploring the examine frontiers of topology, the most vital advancements of recent arithmetic. The papers conceal quite a lot of topological specialties, together with instruments for the research of crew activities on manifolds, calculations of algebraic K-theory, a consequence on analytic constructions on Lie workforce activities, a presentation of the importance of Dirac operators in smoothing concept, a dialogue of the strong topology of 4-manifolds, a solution to the well-known query approximately symmetries of easily hooked up manifolds, and a clean standpoint at the topological type of linear ameliorations.

A geometric approach to homology theory

The aim of those notes is to provide a geometric therapy of generalized homology and cohomology theories. The significant notion is that of a 'mock bundle', that is the geometric cocycle of a basic cobordism idea, and the most new result's that any homology idea is a generalized bordism idea.

Introduction to Topology: Second Edition

This quantity explains nontrivial purposes of metric house topology to research, truly developing their courting. additionally, issues from ordinary algebraic topology specialize in concrete effects with minimum algebraic formalism. chapters examine metric house and point-set topology; the different 2 chapters discuss algebraic topological fabric.

Parametrized homotopy theory

This publication develops rigorous foundations for parametrized homotopy concept, that is the algebraic topology of areas and spectra which are constantly parametrized through the issues of a base house. It additionally starts off the systematic research of parametrized homology and cohomology theories. The parametrized global offers the ordinary domestic for lots of classical notions and effects, resembling orientation idea, the Thom isomorphism, Atiyah and Poincaré duality, move maps, the Adams and Wirthmüller isomorphisms, and the Serre and Eilenberg-Moore spectral sequences.
