| Research Abstract |
1. A certain class of self-adjoint operators is induced by submodules of the Hardy space over the bidisk. These operators are called defect operators. We studied eigenvalues and eigenfunctions of defect operators perturbed by biholomorphic maps.
2. A class of reproducing kernel Hilbert spaces can be constructed from graphs by a canonical way. We studied relation between their Gram matrices and Laplace matrices. Further, we introduced de Branges-Rovnyak theory into graph theory, and showed that it would be an appropriate framework dealing with graph homomorphisms.
