A P-theorem for Inverse Semigroupoids through Ordered Globalizations
Felipe Augusto Tasca, Paulinho Demeneghi, Víctor Marín +1
We prove that every ordered partial action of an inverse semigroupoid on a partially ordered set admits a globalization. This result is used to establish a connection between order…

Globalization of partial inverse semigroupoid actions on sets
Paulinho Demeneghi, Felipe Augusto Tasca
We prove that every partial action of an inverse semigroupoid on a set admits a universal globalization. Moreover, we show that our construction gives a reflector from the category…

The Ideal Structure of Steinberg Algebras
Paulinho Demeneghi
Given an ample action of an inverse semigroup on a locally compact and Hausdorff topological space, we study the ideal structure of the crossed product algebra associated with it.…
