| Research Abstract |
Nishida has studied the elliptic cohomology theory and the theory of modular forms from the homotopical view point following the study of the previous year. A relation between the ring of modular forms and the real cohomology of a certain space was already known, but this year we studied this relation for the mod p case. As one result, we have shown that the trace formula for the Hecke operators after reducing mod p, can be described by the mod p cohomology of the space mentioned above using the Steenrod operations.
On the other hand the theory of p-adic modular forms defined by Serre is closely related to the K-theory. We have defined a p-adic completion of the above space using the mod p K-theory and computed the stable homotopy group. This p-adic homotopy group is quite similar to the group of p-adic modular forms and we hope that these are actually isomorphic.
