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…

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…
