Polynomial growth and property for étale groupoids with applications to -theory
Are Austad, Eduard Ortega, Mathias Palmstrøm
We investigate property for étale groupoids and apply it to -theory of reduced groupoid -operator algebras. In particular, under the assumption of polynomial growth,…
Rigidity of twisted groupoid L^p-operator algebras
Einar V. Hetland, Eduard Ortega
In this paper we will study the isomorphism problem for the reduced twisted group and groupoid -operator algebras. For a locally compact group and a continuous 2-cocycle $…
Zappa-Szép products for partial actions of groupoids on Left Cancellative Small Categories
Eduard Ortega, Enrique Pardo
We study groupoid actions on left cancellative small categories and their associated Zappa-Szép products. We show that certain left cancellative small categories with nice length f…
Groupoids and Hermitian Banach *-algebras
Are Austad, Eduard Ortega
We study when the twisted groupoid Banach -algebra is Hermitian. In particular, we prove that Hermitian groupoids satisfy the weak containment property. Fur…
The homology of the groupoid of the self-similar dihedral group
Eduard Ortega, Alvaro Sanchez
We give an example of a locally compact effective Hausdorff, minimal ample groupoid such that its rational homology differs from the -theory of its reduced groupoid -algebr…
Katsura--Exel--Pardo Groupoids and the AH~Conjecture
Petter Nyland, Eduard Ortega
It is proven that Matui's AH~conjecture is true for Katsura--Exel--Pardo groupoids associated to integral matrices and . This conjecture relates the topo…
