John Quigg: CP all the way up

Abstract: We present a new method of showing that a k-graph C*-algebra is the Cuntz-Pimsner algebra of a correspondence over a (k-1)-graph algebra, using Menevse's functor from the correspondence category of correspondences, together with Valentin's iterative procedure for the Cuntz-Pimsner construction. One innovative aspect is that we go from the bottom up rather than from the top down. Work in progress. Joint work with Valentin Deaconu, Menevse Eryuzlu Paulovicks, and S. Kaliszewski.
