Virtual cycles of 3-term complexes and the Hilbert schemes of surfaces
Emilio Dominguez, Amin Gholampour
Given a 3-term perfect complex E over a quasi-projective variety X and a nonnegative integer r, we define two virtual cycles and their refinements supported over the r-th degenerac…

Barabasi-Albert trees are hypoenergetic
Octavio Arizmendi, Emilio Dominguez
We prove that graphs following the model of Barabasi-Albert tree with n vertices are hypoenergetic in the large n limit.
