I shall begin with (classical) results on vector valued (cuspidal) Siegel modular forms by Tshushima, Satoh and Ibukiyama, respectively. The first one computes the dimension of cusp form spaces and the latter two describe the space of Siegel modular forms w.r.t. Sym^2 and Sp(2,Z). Afterwards I shall present new structure theorems for vector valued Siegel modular forms with respect to Sym^2 and Igusa's subgroup \Gamma_2[2,4]. For the proof we shall observe meromorphic tensors on the projective space P^3C with a particular pole behaviour similar to logarithmic poles. I am planning to restrict myself to 60 minutes. Depending on the audience the talk will be either in German or English.
