Scalar-valued depth two Eichler-Shimura Integrals of Cusp Forms

Tobias Magnusson, Martin Raum

Given cusp forms and of integral weight , the depth two holomorphic iterated Eichler-Shimura integral is defined by ${\int_τ^{i\infty}f(z)(X-z)^{k-2}I_g…

A classification of polyharmonic Maaß forms via quiver representations

Claudia Alfes-Neumann, Igor Burban, Martin Raum

We give a classification of the Harish-Chandra modules generated by the pullback to~$\SL{2}(\RR)$ of \emph{poly}harmonic Maaß forms for congruence subgroups of~$\SL{2}(\ZZ)$ with e…

The Bernstein-Gelfand Tensor Product Functor and the Weight-2 Eisenstein Series

Martin Raum

The Bernstein-Gelfand tensor product functors are endofunctors of the category of Harish-Chandra modules provided by tensor products with finite dimensional modules. We provide an…

Eichler integrals and generalized second order Eisenstein series

Albin Ahlbäck, Tobias Magnusson, Martin Raum

We show that all Eichler integrals, and more generally all "generalized second order modular forms" can be expressed as linear combinations of corresponding generalized second orde…

Congruences of Hurwitz class numbers on square classes

Olivia Beckwith, Martin Raum, Olav Richter

We extend a holomorphic projection argument of our earlier work to prove a novel divisibility result for non-holomorphic congruences of Hurwitz class numbers. This result allows us…

On the Computation of General Vector-valued Modular Forms

Tobias Magnusson, Martin Raum

We present and discuss an algorithm and its implementation that is capable of directly determining Fourier expansions of any vector-valued modular form of weight at least assoc…
