Spectral theory provides a rigorous framework for analysing the eigenvalues and eigenfunctions of differential operators that play an essential role in mathematical physics. In particular, ...

The notion of spectral invariance of a locally convex *-algebra is defined by constructing the enveloping C*-algebra and is characterized. It is shown that the spectral invariance induces K-theory ...

My general research interest is in the area of combinatorics (graph theory) and algebra. My first exposure to research is through graph labeling when I was an undergraduate student. During my PhD, I ...
