Theta blocks related to root systems
Moritz Dittmann, Haowu Wang
Gritsenko, Skoruppa and Zagier associated to a root system a theta block , which is a Jacobi form of lattice index. We classify the theta blocks of $…
Harmonic theta series and the Kodaira dimension of
Moritz Dittmann, Riccardo Salvati Manni, Nils R. Scheithauer
We construct a basis of the space of Siegel cusp forms of degree and weight consisting of harmonic theta series. One of the…
Reflective automorphic forms on lattices of squarefree level
Moritz Dittmann
We show that there are only finitely many nonconstant reflective automorphic forms on even lattices of squarefree level splitting two hyperbolic planes and give a complete clas…
Automorphic products of singular weight for simple lattices
Moritz Dittmann, Heike Hagemeier, Markus Schwagenscheidt
We classify the simple even lattices of square free level and signature (2,n) for n > 3. A lattice is called simple if the space of cusp forms of weight 1+n/2 for the dual Weil rep…
