Discrete Morse theory for computing cellular sheaf cohomology
Published 23 Dec 2013 in math.AT | (1312.6454v2)
Abstract: Sheaves and sheaf cohomology are powerful tools in computational topology, greatly generalizing persistent homology. We develop an algorithm for simplifying the computation of cellular sheaf cohomology via (discrete) Morse-theoretic techniques. As a consequence, we derive efficient techniques for distributed computation of (ordinary) cohomology of a cell complex.
