Nilpotence and Periodicity in Stable Homotopy Theory. by Douglas C. Ravenel

By Douglas C. Ravenel

Nilpotence and Periodicity in solid Homotopy thought describes a few significant advances made in algebraic topology lately, centering at the nilpotence and periodicity theorems, that have been conjectured by way of the writer in 1977 and proved by means of Devinatz, Hopkins, and Smith in 1985. over the past ten years a few major advances were made in homotopy idea, and this publication fills a true want for an up to date textual content on that subject.

Ravenel's first few chapters are written with a basic mathematical viewers in brain. They survey either the information that lead as much as the theorems and their purposes to homotopy thought. The ebook starts off with a few user-friendly innovations of homotopy idea which are had to nation the matter. This contains such notions as homotopy, homotopy equivalence, CW-complex, and suspension. subsequent the equipment of advanced cobordism, Morava K-theory, and formal crew legislation in attribute p are brought. The latter part of the e-book presents experts with a coherent and rigorous account of the proofs. It contains hitherto unpublished fabric at the ruin product and chromatic convergence theorems and on modular representations of the symmetric workforce.

Riemann Surfaces

The speculation of Riemann surfaces occupies a truly detailed position in arithmetic. it's a fruits of a lot of conventional calculus, making miraculous connections with geometry and mathematics. it's an exceptionally precious a part of arithmetic, wisdom of that is wanted by way of experts in lots of different fields.

Residues and duality for projective algebraic varieties

This booklet, which grew out of lectures via E. Kunz for college kids with a history in algebra and algebraic geometry, develops neighborhood and worldwide duality conception within the certain case of (possibly singular) algebraic kinds over algebraically closed base fields. It describes duality and residue theorems by way of Kahler differential kinds and their residues.
