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.…
Global product structure for a space of special matrices
Horacio Leyva, Francisco A. Carrillo, Baltazar Aguirre-Hernández +1
The importance of the Hurwitz Metzler matrices and the Hurwitz symmetric matrices can be appreciated in different applications: communication networks, biology and economics are so…
Collapsibility and homological properties of -contractible transformations
Jesus F. Espinoza, Martín-Eduardo Frías-Armenta, Héctor A. Hernández
The family of -contractible graphs and contractible transformations was defined by A. Ivashchenko in the mid-90's. In this paper we study the collapsibility and homol…
