Graded C*-algebras, graded K-theory, and twisted P-graph C*-algebras
Alex Kumjian, David Pask, Aidan Sims
We develop methods for computing graded K-theory of C*-algebras as defined in terms of Kasparov theory. We establish graded versions of Pimsner's six-term sequences for graded Hilb…

Unbounded quasitraces, stable finiteness and pure infiniteness
David Pask, Adam Sierakowski, Aidan Sims
We prove that if A is a σ-unital exact C*-algebra of real rank zero, then every state on K_0(A) is induced by a 2-quasitrace on A. This yields a generalisation of Rainone's work on…
