Covariants of binary sextics and modular forms of degree 2 with character
Fabien Cléry, Carel Faber, Gerard van der Geer
We use covariants of binary sextics to describe the structure of modules of scalar-valued or vector-valued Siegel modular forms of degree 2 with character, over the ring of scalar-…
Covariants of binary sextics and vector-valued Siegel modular forms of genus two
Fabien Cléry, Carel Faber, Gerard van der Geer
We extend Igusa's description of the relation between invariants of binary sextics and Siegel modular forms of degree two to a relation between covariants and vector-valued Siegel…
Generators for modules of vector-valued Picard modular forms
Fabien Cléry, Gerard van der Geer
We construct generators for modules of vector-valued Picard modular forms on a unitary group of type (2,1) over the Eisenstein integers. We also calculate eigenvalues of Hecke oper…
Modular forms of orthogonal type and Jacobi theta-series
Fabien Clery, Valery Gritsenko
In this paper we consider Jacobi forms of half-integral index for any positive definite lattice L (classical Jacobi forms from the book of Eichler and Zagier correspond to the latt…
The Siegel modular forms of genus 2 with the simplest divisor
Valery Gritsenko, Fabien Clery
We prove that there exist exactly eight Siegel modular forms with respect to the congruence subgroups of Hecke type of the paramodular groups of genus two vanishing precisely along…
