K-homology of certain group C*-algebras
Tom Hadfield
Motivated by the search for new examples of ``noncommutative manifolds'', we study the noncommutative geometry (in the sense of Connes) of the group C*-algebras of various discrete…
The noncommutative geometry of the discrete Heisenberg group
Tom Hadfield
Motivated by the search for new examples of ``noncommutative manifolds'', we study the noncommutative geometry (in the sense of Connes) of the group C*-algebra of the three dimensi…
K-homology of the CAR algebra
Tom Hadfield
We compare the K-theory and K-homology of the well known CAR algebra. While the group is infinitely generated, we shows that it pairs identically to zero with even Fredholm m…
K-homology of the rotation algebras
Tom Hadfield
We study the K-homology of the rotation algebras using the six term cyclic sequence for the K-homology of a crossed product by . In the case where is irrational…
Fredholm modules over certain group C*-algebras
Tom Hadfield
Motivated by the search for new examples of "noncommutative manifolds", we study the noncommutative geometry of the group C*-algebras of various discrete groups. The examples we co…
