 Ely Kerman (UIUC)J-holomorphic cylinders between ellipsoidsAbstract: The primary tool for detecting obstructions to symplectic embeddings are regular J-holomorphic curves in symplectic cobordisms. The more the better. In this talk, I will describe an existence theorem for such curves in dimension 4 and, time permitting, an application. This is based on joint work in progress with Richard Hind.

 Cristian Ortiz (University of Sao Paulo)Geometric Lie 2-algebrasAbstract: Lie 2-algebras were introduced by Baez and Crans as groupoid objects in the category of Lie algebras. In this talk we will present a class of examples of Lie 2-algebras, those coming from sections of LA-groupoids. We will see that the category of sections of an LA-groupoid has a natural structure of Lie 2-algebra which is Morita invariant in a suitable sense. In the particular case of the tangent groupoid, one gets a Lie 2-algebra structure on the category of multiplicative vector fields on a Lie groupoid. We will explain how this can be used to introduce a geometric notion of vector field on the quotient stack of a Lie groupoid. This is joint work with James Waldron.

 Ralph Klaasse (Utrecht University)Constructing A-symplectic structuresAbstract: In this talk we discuss how to construct A-symplectic structures for a Lie algebroid A by adapting Gompf-Thurston techniques to Lie algebroid morphisms. As an application we obtain both log-symplectic and stable generalized complex structures out of log-symplectic structures. In particular we define a class of maps called boundary Lefschetz fibrations and show they equip their total space with a stable generalized complex structure. This is based on joint work with Gil Cavalcanti.

 Jean Gutt (University of Georgia)"The minimal number of periodic Reeb orbits as a cuplengthAbstract: I will present the recent result with P.Albers and D.Hein that every graphical hypersurface in a prequantization bundle over a symplectic manifold M pinched between two circle bundles whose ratio of radii is less than \sqrt{2} carries either one short simple periodic orbit or carries at least cuplength(M)+1 simple periodic Reeb orbits.
