2013/03/11	Geometrically proven structure theorems for vector valued Siegel modular forms,
	27th Automorphic Forms Workshop
	show / hide details 20 minutes projector talk abstract : "It is well known that \Gamma-invariant tensor fields on the Siegel upper halfplane can be viewed as vector valued Siegel modular forms with respect to this group \Gamma. We consider one of Igusa's subgroups for which the Satake compactification is the 3-dimensional projective space. After observing the tensors on the Satake compactification the structure theorem(s) and Hilbert function(s) for the representation Sym^2 become rather evident."

	University of Heidelberg

2013/02/06	Structure theorems for vector valued Siegel modular forms derived from complex geometry,
	Hauptseminar Modulformen,
	Ruprecht-Karls-Universität Heidelberg
	show / hide details 70 minutes black board talk abstract : "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." as anounced at http://www.mathi.uni-heidelberg.de/events/showevent?eventid=1150.
