| Research Abstract |
Our aim on this project is to determine the structure of automorphic forms by using differential operators. In this two years, we have the following two results :
(1) On the structure of Hilbert modular forms with respect to a real quadratic field with small discriminant, we have a structure theorem when the difference of the weight is small.
(2) On the structure of vector valued Siegel modular forms of degree 2, we have a structure theorem when the discrete subgroup is in a congruent subgroup with a small level.
