Research Abstract |
The feature of our work is that we study Dedekind symbols in the relation with modular forms. Thus it is a significant step that we have constructed nice bases for the vector spaces of modular forms. We also obtained formulas to express powers of the theta function in terms of Eisenstein series. These formulas give us formulas for the numbers of representations of integers as sums of squares. These seem interesting from number theoretical and geometrical view points.
