C*-algebras of groupoid morphisms
Bruno Tadeu Costa, Renan Gambale Romano, Felipe Vieira
In this paper we suggest a definition for a C*-algebra attached to an injective morphism of some Étale groupoid. We take into account all the peculiarities of such objects and pres…
C*-algebras of endomorphisms of groups with finite cokernel and partial actions
Felipe Vieira
In this paper we extend the constructions of Boava and Exel to present the C*-algebra associated with an injective endomorphism of a group with finite cokernel as a partial group a…
Universal C*-algebras of endomorphisms of groups and partial actions
Felipe Vieira
We present a different way to study the C*-algebra associated with an injective endomorphism of a group G of infinite cokernel. We follow the work of Boava and Exel to construct a…
Partial Crossed Product of a group G vs Crossed Product of S(G)
Ruy Exel, Felipe Vieira
In this work we present a new definition to the Partial Crossed Product by actions of inverse semigroups in a C^*-algebra, without using the covariant representations as Sieben did…
