Research Abstract

The head investigator worked on the following topics :
1. We introduced modular forms in several variables on finite upper half planes, and studied Eisenstein series.
2. We established the recurrence formulas for multi-poly- Bernoulli numbers.
3. We obtained some Siegel subvarieties of codimension one, which are of general type, under certain conditions of the type of polarization.
Other investigators got some results: T. Agoh established a quadratic recurrence formula of new type for Bernoulli numbers. H. Aoki determined some rings of vector valued Siegel modular forms. T. Gotoh obtained some results on the existence of unitary perfect and harmonic numbers.
