The Whitney method of fundamental solutions with Lusin wavelets
Jakob Jonsson, Andreas Rosén, Emil Timlin
We establish the theoretical foundation for a variant of the method of fundamental solutions (MFS), where the source points accumulate towards the domain in…
The exact chromatic number of the convex segment disjointness graph
Ruy Fabila-Monroy, Jakob Jonsson, Pavel Valtr +1
Let be a set of points in strictly convex position in the plane. Let be the graph whose vertex set is the set of all line segments with endpoints in , where disjoi…
More Torsion in the Homology of the Matching Complex
Jakob Jonsson
A matching on a set is a collection of pairwise disjoint subsets of of size two. Using computers, we analyze the integral homology of the matching complex , which is t…
Five-Torsion in the Homology of the Matching Complex on 14 Vertices
Jakob Jonsson
J. L. Andersen proved that there is 5-torsion in the bottom nonvanishing homology group of the simplicial complex of graphs of degree at most two on seven vertices. We use this res…
On the 3-torsion Part of the Homology of the Chessboard Complex
Jakob Jonsson
Let . We prove various results about the chessboard complex , which is the simplicial complex of matchings in the complete bipartite graph . First,…
Exact Sequences for the Homology of the Matching Complex
Jakob Jonsson
Building on work by Bouc and by Shareshian and Wachs, we provide a toolbox of long exact sequences for the reduced simplicial homology of the matching complex , which is the s…
