On the -theory of groups of the form with square-free
Luis Jorge Sánchez Saldaña, Mario Velásquez
We provide an explicit computation of the topological -theory groups of semidirect products of the form $\mathbb{Z}^n\rtimes \math…
Hecke operators in Bredon (co)homology, K-(co)homology and Bianchi groups
David Muñoz, Jorge Plazas, Mario Velásquez
In this article we provide a framework for the study of Hecke operators acting on the Bredon (co)homology of an arithmetic discrete group. Our main interest lies in the study of He…
The topological K-theory of crystallographic groups with holonomy
Mario Velásquez
In this note we present a complete computation of the topological K-theory of the reduced C*-algebra of a semidirect product of the form with…
Induced character in equivariant K-theory and wreath products
Germán Combariza, Juan Rodríguez, Mario Velásquez
Let be a finite group, be a compact -space. In this note we study the -graded algebra $$\mathcal{F}^q_G(X) = \bigoplus_{n\g…
The algebraic and topological K-theory of the Hilbert Modular Group
Luis Jorge Sánchez Saldaña, Mario Velásquez
In this paper we provide descriptions of the Whitehead groups with coefficients in a ring of the Hilbert modular group and its reduced version, as well as for the topological K-the…
