Proved a Lusternik-Schnirelmann theorem for matchings on posets.
Unified concepts from discrete Morse-Bott theory and Morse theory.
Abstract
We develop Morse-Bott theory on posets, generalizing both discrete Morse-Bott theory for regular complexes and Morse theory on posets. Moreover, we prove a Lusternik-Schnirelmann theorem for general matchings on posets, in particular, for Morse-Bott functions.
