Algebraic properties of edge ideals via combinatorial topology
Anton Dochtermann, Alexander Engstrom
We apply some basic notions from combinatorial topology to establish various algebraic properties of edge ideals of graphs and more general Stanley-Reisner rings. In this way we pr…

Upper bounds on the Witten index for supersymmetric lattice models by discrete Morse theory
Alexander Engstrom
The Witten index for certain supersymmetric lattice models treated by de Boer, van Eerten, Fendley, and Schoutens, can be formulated as a topological invariant of simplicial comple…
