The structure of Siegel modular forms modulo p and U(p) congruences
Martin Raum, Olav Richter
We determine the ring structure of Siegel modular forms of degree g modulo a prime p, extending Nagaoka's result in the case of degree g=2. We characterize U(p) congruences of Jaco…

Holomorphic projections and Ramanujan's mock theta functions
Özlem Imamoglu, Martin Raum, Olav K. Richter
We employ spectral methods of automorphic forms to establish a holomorphic projection operator for tensor products of vector-valued harmonic weak Maass forms and vector-valued modu…

Spans of special cycles of codimension less than 5
Martin Raum
We show that the span of special cycles in the th Chow group of a Shimura variety of orthogonal type is finite dimensional, if . As our main tool, we develop the theory o…
