Linear-size graphs at every strict dismantling level
Jesús F. Espinoza, Martín Eduardo Frías-Armenta, Rosalía G. Hernández-Amador +1
Dismantling reduces a graph to one vertex by successive deletions. At level zero, a vertex is eligible if one of its neighbours is adjacent to all its other neighbours. At level $k…

A numerical approach for the filtered generalized Cech complex
Jesus F. Espinoza, Rosalia Hernandez-Amador, Hector A. Hernandez +1
In this paper, we present an algorithm to compute the filtered generalized Čech complex for a finite collection of disks in the plane, which don't necessarily have the same radius.…
