Congruences for Siegel modular forms of nonquadratic nebentypus mod $p$

Siegfried Boecherer, Toshiyuki Kikuta

We prove that weights of two Siegel modular forms of nonquadratic nebentypus should satisfy some congruence relations if these modular forms are congruent to each other. Applying t…

Weights of the mod $p$ kernel of the theta operators

Siegfried Boecherer, Toshiyuki Kikuta, Sho Takemori

We give some relations between the weights and the prime $p$ of elements of the mod $p$ kernel of the generalized theta operator $Θ^{[j]}$ . In order to construct examples of the mo…

On theta series attached to maximal lattices and their adjoints

Siegfried Boecherer, Gabriele Nebe

The space spanned by theta series of adjoints of maximal even lattices of exact level $N$ and determinant $N^{2}$ has the Weierstrass property and hence allows to define extremality…
