Title: On amplified graph C*-algebras as cores of Cuntz-Krieger algebras
Abstract: We consider directed graphs in which, whenever there is an edge between two vertices, there are infinitely many edges; these are called amplified graphs. In this talk, given an amplified graph F satisfying suitable conditions, I will show how to construct a graph E such that the graph C*-algebra C*(F) is isomorphic to the core C*(E)^{U(1)}. This work is motivated by the study of noncommutative analogues of classical spaces. As an example, I will describe how the noncommutative Grassmannian C(Gr_q(2,4)) can be realized as the core of a graph C*-algebra and use this description to analyse its noncommutative CW-structure.
The talk is based on joint work with Francesco D'Andrea.
