This self-contained remedy of Morse thought specializes in functions and is meant for a graduate direction on differential or algebraic topology. The booklet is split into 3 conceptually precise elements. the 1st half comprises the rules of Morse idea. the second one half involves purposes of Morse thought over the reals, whereas the final half describes the fundamentals and a few functions of advanced Morse conception, a.k.a. Picard-Lefschetz theory.

This is the 1st textbook to incorporate subject matters equivalent to Morse-Smale flows, Floer homology, min-max thought, second maps and equivariant cohomology, and intricate Morse idea. The exposition is more suitable with examples, difficulties, and illustrations, and should be of curiosity to graduate scholars in addition to researchers. The reader is anticipated to have a few familiarity with cohomology idea and with the differential and crucial calculus on gentle manifolds.

Some positive aspects of the second one variation contain extra purposes, akin to Morse idea and the curvature of knots, the cohomology of the moduli area of planar polygons, and the Duistermaat-Heckman formulation. the second one variation additionally contains a new bankruptcy on Morse-Smale flows and Whitney stratifications, many new routines, and numerous corrections from the 1st variation.

Elliptic cohomology is a really appealing concept with either geometric and mathematics elements. the previous is defined by means of the truth that the idea is a quotient of orientated cobordism localised clear of 2, the latter by way of the truth that the coefficients coincide with a hoop of modular types. the purpose of the e-book is to build this cohomology conception, and assessment it on classifying areas BG of finite teams G.
