Equivariant spectral triples for and the odd dimensional quantum spheres
Partha Sarathi Chakraborty, Arupkumar Pal
We formulate the notion of equivariance of an operator with respect to a covariant representation of a C^*-dynamical system. We then use a combinatorial technique used by the autho…
Characterization of spectral triples: A combinatorial approach
Partha Sarathi Chakraborty, Arupkumar Pal
We describe a general technique to study Dirac operators on noncommutative spaces under some additional assumptions. The main idea is to capture the compact resolvent condition in…
Equivariant spectral triples on the quantum SU(2) group
Partha Sarathi Chakraborty, Arupkumar Pal
We characterize all equivariant odd spectral triples for the quantum SU(2) group acting on its L_2-space and having a nontrivial Chern character. It is shown that the dimension of…
Regular Operators on Hilbert C^*-modules
Arupkumar Pal
A regular operator T on a Hilbert C^*-module is defined just like a closed operator on a Hilbert space, with the extra condition that the range of (I+T^*T) is dense. Semiregular op…
