Applications of Lusternik-Schnirelmann category and its generalizations. (English) Zbl 1330.55002

The author describes diverse applications of the category of a topological space (in the sense of Lusternik and Schnirelmann) to various areas of mathematics. For example: Brouwer fixed point theorem, Morse theory, Symplectic geometry, Nonnegative Ricci curvature, Smale topological complexity, etc.
