As a part of the clinical job in reference to the seventieth birthday of the Adam Mickiewicz collage in Poznan, a global convention on algebraic topology was once held. within the ensuing complaints quantity, the emphasis is on enormous survey papers, a few offered on the convention, a few written subsequently.

**Geometry of Characteristic Classes (Translations of Mathematical Monographs)**

Attribute periods are relevant to the trendy research of the topology and geometry of manifolds. They have been first brought in topology, the place, for example, they can be used to outline obstructions to the life of sure fiber bundles. attribute periods have been later outlined (via the Chern-Weil concept) utilizing connections on vector bundles, hence revealing their geometric facet.

This publication develops rigorous foundations for parametrized homotopy concept, that's the algebraic topology of areas and spectra which are consistently parametrized by means of the issues of a base area. It additionally starts the systematic research of parametrized homology and cohomology theories. The parametrized international presents the average domestic for lots of classical notions and effects, resembling orientation thought, the Thom isomorphism, Atiyah and Poincaré duality, move maps, the Adams and Wirthmüller isomorphisms, and the Serre and Eilenberg-Moore spectral sequences.

**Models for Smooth Infinitesimal Analysis**

The purpose of this e-book is to build different types of areas which include the entire C? -manifolds, but also infinitesimal areas and arbitrary functionality areas. To this finish, the recommendations of Grothendieck toposes (and the good judgment inherent to them) are defined at a leisurely speed and utilized. via discussing themes corresponding to integration, cohomology and vector bundles within the new context, the adequacy of those new areas for research and geometry may be illustrated and the relationship to the classical method of C?

This obstruction vanishes in the case that the base of ~ is a double suspension. In all the classical cases, ~he base is a highly connected sphere and the obstruction vanishes: T S 3 - T h e structure of T2 43 Given a presentation B = B2 = ((* U C A o ) U CA1 ), the following presentation is obtained: T = T2 = ((T(*) U C(Ao A T(*))) U C(A1 AT(*))), with attaching maps T ( f l ) mid T(f2). Thus, as T ( f l ) is known, only T(f~) is needed in order to give a full description of T2. The main theorem of [Hal], was shown in [D, I, §6], to describe the homotopy class of the relative attaching map Po o T(f2), (in the case that A1 is a suspension) which is an element in the set [A1 AT(*}, EA0 AT(*}].

1 ). We also need the notion of so-called equivariant Euler characteristic which is the UFAI for the category of finite G-complexes. First we define a functor A G : G-Top ---+ Ab. For G-space X we put AG(X) to be the free abelian group generated by the set CI(X). A G-map f : X ---* Y induces a homomorphism AG(f):AG(X) --. A G ( y ) . Let X be a G-space that is finitely G-dominated. o(WH)*]) cI(x) and wa(X) = ~ w~(X) . 3 (a) The pair (AG,x G) is the UFAI for the category of G-spaces having the G-homotopy type of a finite G-complex.
