Mock Maass Forms Revisited
Yingkun Li, Christina Roehrig
In this paper, we use theta integrals to give a different construction of mock Maass forms studied by Sander Zwegers. With this method, we construct new real-analytic modular forms…
Theta Series for Quadratic Forms of Signature with (Spherical) Polynomials II
Christina Roehrig, Sander Zwegers
We generalize the construction from arXiv:2102.09329 of theta series for quadratic forms of signature with homogeneous and spherical polynomials. Namely, we allow that th…
Siegel theta series for quadratic forms of signature
Christina Roehrig
We investigate Siegel theta series for quadratic forms of signature . On the one hand, we construct a holomorphic series that does not transform like a modular form. On th…
Theta Series for Quadratic Forms of Signature with (Spherical) Polynomials
Christina Roehrig, Sander Zwegers
We construct almost holomorphic and holomorphic modular forms by considering theta series for quadratic forms of signature . We include homogeneous and spherical polynomia…
Siegel theta series for indefinite quadratic forms
Christina Roehrig
The modular transformation behavior of theta series for indefinite quadratic forms is well understood in the case of elliptic modular forms due to Vignéras, who deduced that solvin…
