Discrete Morse Theory on Simplicial Complexes

Discrete Morse Theory on Simplicial Complexes August 27,2009 ALEXZORN ABSTRACT: Following [2]and[3], we introducea combinatorial analog of topological Morse theory, and show how the introduction of a discrete Morse function on a simplicial complex gives rise to a discrete vector eld.

MISTAKE IN HIRSCH'SPROOF OF THE BROUWER FIXED POINT THEOREM

Although the Simplicial Approximation Theorem gives a simplicial approximation to every continuous map (between nite polyhedra), nowhere does it say that a simplicial approximation to a retraction is, or can be chosen to be, a simplicial retraction.
