The Doubling Method in Algebraic Families
Johannes Girsch
We define the doubling zeta integral for smooth families of representations of classical groups. Following this we prove a rationality result for these zeta integrals and show that…

Class invariants for certain non-holomorphic modular functions
Joschka J. Braun, Johannes J. Buck, Johannes Girsch
Inspired by prior work of Bruinier and Ono and Mertens and Rolen, we study class polynomials for non-holomorphic modular functions arising from modular forms of negative weight. In…
