Dimension formulas for spaces of vector-valued Siegel modular forms of degree two and level two
Using a description of the cohomology of local systems on the moduli space of abelian surfaces with a full level two structure, together with a computation of Euler characteristics we find the isotypical decomposition, under the symmetric group on 6 letters, of spaces of vector-valued Siegel modular...

Summary: | Using a description of the cohomology of local systems on the moduli space of
abelian surfaces with a full level two structure, together with a computation
of Euler characteristics we find the isotypical decomposition, under the
symmetric group on 6 letters, of spaces of vector-valued Siegel modular forms
of degree two and level two. |
