Abstract: |
There is a famous correspondence by Shimura between elliptic modular forms
of integral weight and of half-integral weight.
What happens when we take Siegel modular forms of level one of degree two?
A very concrete conjectural answer on this is a subject of the talk.
Also, we give a conjectural congruence between
Siegel modular forms of half-integral weight, which corresponds to the one
conjectured by Harder for integral weight. |
