| Outline of Final Research Achievements |
We have work in the boundary between the theory of modular forms and that of algebraic combinatorics. With Masashi Kosusa, we determined the structures of the centralizer rings of the tensor representation of the group associated to Type II binary codes. With Togo Motomura, we determined the generators of the garded ring of E-polynomials associated to Type II Z4-codes. With Michio Ozeki, we studied the theta series of five extremal Type II lattices of rank 85 and showed that they are distinct in genus four.
