Tracing cyclic homology pairings under twisting of graded algebras

  • Sayan Chakraborty
  • Makoto YamashitaEmail author


We give a description of cyclic cohomology and its pairing with K-groups for 2-cocycle deformation of algebras graded over discrete groups. The proof relies on a realization of monodromy for the Gauss–Manin connection on periodic cyclic cohomology in terms of the cup product action of group cohomology.
