The groupoid semigroup and its application
In this talk, I will introduce and discuss an algebraic tool called the groupoid semigroup. I will show how this semigroup help establishing the almost unperforation form for dynamical comparison. Then, I will show how it relates to the type semigroup in the ample case. Finally, I will present some result on (strongly) pure infiniteness of reduced groupoid C*-algebras.
