Symplectic Geometry Seminar

Titel Sharp systolic inequalities in Riemannian geometry and Reeb dynamics
Referent:in, Affiliation Alberto Abbondandolo, Ruhr-Universität Bochum
Datum, Zeit 2. März 2015, 15:15-16:30
Ort HG G 43
Abstract A classical question in Riemannian geometry is to find a sharp upper bound for the ratio of the square of the length of the shortest closed geodesic on a two-sphere by the area of the sphere. I shall discuss how symplectic techniques can be used in order to determine sharp upper bounds for metrics which are sufficiently pinched. I shall also argue that the natural setting for questions of this kind is Reeb dynamics and discuss some results in this setting.

Titel Homological Mirror Symmetry for Singularities of type Tpqr
Referent:in, Affiliation Ailsa Keating, Columbia University, USA
Datum, Zeit 16. März 2015, 15:15-16:30
Ort HG G 43
Abstract We present some versions of mirror symmetry for the unimodal singularities of type $T_{p,q,r}$. We will consider some symplectic invariants of the real four-dimensional Milnor fibres of these singularities, and explain how they correspond to coherent sheaves on certain blow-ups of the projective space $\P^2$. Time allowing, we hope to emphasize how the relations between different ``flavours" of invariants (e.g., versions of the Fukaya category) match up on both sides.

Referent:in, Affiliation Peter Albers, Universität Münster
Datum, Zeit 11. Mai 2015, 15:15-16:30
Ort HG G 43
Abstract In this talk I will present a general cuplength estimate using Morse- and Floer theoretic methods. From this several (mostly known) results in symplectic geometry follow immediately. The method of proof can be extracted from various sources in the literature. Thus the talk will be mostly educational (I hope.) This is joint work with Doris Hein.
