On the centroid of a Leavitt path algebra
Daniel Gonçalves, Dolores Martín Barquero, Cándido Martín González +1
We describe the centroid of some Leavitt path algebras. More precisely, we show that for Leavitt path algebras over a field that are simple its centroid is isomorphic to , a…
Topological full groups of ultragraph groupoids as an isomorphism invariant
Gilles Gonçalves de Castro, Daniel Gonçalves, Daniel W van Wyk
We prove two isomorphism-invariance theorems for groupoids associated with ultragraphs. These theorems characterize ultragraphs for which the topological full group of an associate…
The interplay between Steinberg algebras and partial skew rings
Viviane Beuter, Daniel Gonçalves
We study the interplay between Steinberg algebras and partial skew rings: For a partial action of a group in a Hausdorff, locally compact, totally disconnected topological space, w…
On triangles in K_r-minor free graphs
Boris Albar, Daniel Gonçalves
We study graphs where each edge adjacent to a vertex of small degree (7 and 9, respectively) belongs to many triangles (4 and 5, respectively) and show that these graphs contain a…
