| Outline of Final Research Achievements |
By considering a graph as a matrix such as an Adjacency matrix or Laplacian matrix, we can study the structure with the linear algebra. In this research, we investigated the structure of graphs when eigenvalues are restricted, and challenged to explore a new research area by using the reproducing kernel Hilbert space theory.
When considering the rough keyword "eigenvalue", there exist various mathematical research fields. When considering the discrete structure, it is because graph appear naturally. We have held research meetings every year to gather researchers who are studying graph eigenvalues in various mathematical areas and share information.
