DVF and homology of h-regular finite topological spaces #30862

Open jcuevas-rozo opened 4 years ago

jcuevas-rozo commented 4 years ago

This is a continuation of the work started in tickets #30400, #30447. It is expected to add methods about computing homology groups of h-regular spaces. Also, the computation of homologically admissible Morse matchings (or Discrete Vector Fields, DVF) will be implemented allowing to apply the Discrete Morse Theory for finite spaces described in (1) and (2).

Depends on #30447

CC: @jhpalmieri

Component: algebraic topology

Keywords: Finite topological spaces, Discrete Morse theory

Stalled in needs_review or needs_info; likely won't make it into Sage 9.5.
