Let's say we have a graph (i.e. network), and we want to cluster the vertices (nodes).  Here, think of the nodes as people, agents, oscillators, some dynamic being, and the edges... the edges tell...

In a huge graph, it is hard to determine a bottleneck by just looking at it, or doing any type of search. And by a bottleneck, I mean part of graph that is not very much connected to the other part....

My first solo paper "Existence of a Not Necessarily Symmetric Matrix with Given Distinct Eigenvalues and Graph" got published in Journal of Linear Algebra and its Applications, yesterday. It took it...

For the past several months my Saturdays consist of two meetings, each of which about 4 hours long, with two of my colleagues working on various problems. Clearly we've hit a lot of dead ends, and...

We (Sudipta Mallik and I) just submitted our paper on the "Spectral characterization of matchings in graphs". It is based on our previous work on "Construction of real skew-symmetric matrices from...
