Hermitian theta series and Maaß spaces under the action of the maximal discrete extension of the Hermitian modular group

Annalena Wernz

Let ${\Gamma }_n({\mathcal{O}}_{\mathbb{K}})$ denote the Hermitian modular group of degree $n$ over an imaginary quadratic number field $\mathbb{K}$ and ${\Delta }_{n,\mathbb{K}}^{\ast }$ it…
