Leavitt path algebras and graph C*-algebras

October 13, 2010

Abstract
 

In this talk, we show how one can construct algebras from a graph. In particular, we construct the Leavitt path algebra LC(E) and the graph C*-algebra C*(E) for a given graph E. We discuss the following questions due to Abrams and Tomforde:

  1. Does Morita equivalence of LC(E1) and LC(E2) imply that C*(E1) and C*(E2) are strongly Morita equivalent?
  2. Conversely, does strong Morita equivalence of C*(E1) and C*(E2) imply that LC(E1) and LC(E2) are Morita equivalent?
