| Outline of Final Research Achievements |
We investigated number-theoretical behavior of the Laplacian for certain series of graphs, mainly for Cartesian products of path or cycle graphs. Specifically, we solved a problem of Hunziker-Machiavelo-Park in the affirmative way, conjectured a formula for the dimension of the space of harmonic functions in terms of Chebyshev polynomials, and succeeded in proving the conjecture.
Applying some techniques for polynomials used in the main study, we also obtained some results on a relation between Chebyshev polynomials and twin primes, on the resultant of Chebyshev polynomials and its application, and on isometric embeddings of finite fields.
