Research Areas

  • Combinatorial Matrix Theory
  • I am interested in Combinatorial Matrix Theory. In linear Combinatorial Matrix Theory, researchers study graph structures via different properties of matrices associated with it. Among the various matrices associated with a graph, the adjacency matrix is probably the most popular and widely investigated one. Sometimes different structural properties of a graph gets characterized by different properties of the eigenvalues and the eigenvectors of the associated adjacency matrix. For example, it is well know that ‘a (simple) connected graph G is bipartite if and only if −a is an eigenvalue of G whenever a is an eigenvalue of G’. There are many interesting results exhibiting the relationship of the graph structure with the eigenvalues and eigenvectors.

    I am working to establish such relationships with regard to the concepts of inverse graph and reciprocal eigenvalue properties. In many ways these two concepts are related to each other. Both of these play important roles in quantum chemistry.
