Filtered K-theory for graph algebras

Abstract

We introduce filtered algebraic KK-theory of a ring RR relative to a sublattice of ideals. This is done in such a way that filtered algebraic KK-theory of a Leavitt path algebra relative to the graded ideals is parallel to the gauge invariant filtered KK-theory for graph CC^*-algebras. We apply this to verify the Abrams-Tomforde conjecture for a large class of finite graphs.
