The augmented external activity complex of a matroid
Andrew Berget, Dania Morales
For a matroid, we define a new simplicial complex whose facets are indexed by its independent sets. This complex contains the external activity complex as a subcomplex. We call our…

Existence and nonexistence of positive solutions of quasi-linear elliptic equations with gradient terms
Dania Morales
We study the existence and nonexistence of positive solutions in the whole Euclidean space of coercive quasi-linear elliptic equations such as \[ Δ_p u = f(u)\pm g(\left|\nabla u\r…
