A graded pullback structure of Leavitt path algebras of trimmable graphs (1803.10209v1)
Published 27 Mar 2018 in math.RA and math.OA
Abstract: Motivated by recent results in graph C*-algebras concerning an equivariant pushout structure of the Vaksman-Soibelman quantum odd spheres, we introduce a class of graphs called trimmable. Then we show that the Leavitt path algebra of a trimmable graph is graded-isomorphic to a pullback algebra of simpler Leavitt path algebras and their tensor products.
