Abstract
Using the Steinberg duality between the categories of inverse semigroups and ample groupoids, we prove the triviality (global and local) of the central term of the extension in terms of twisted crossed products.
Subjects
Ample groupoids; inverse semigroups; twisted actions; crossed products
