Kai Cieliebak (Augsburg) Partial orders on contactomorphism groups and their Lie algebras

Eliashberg, Kim and Polterovich constructed nontrivial partial orders on contactomorphism groups of certain contact manifolds. After recalling their results, the subject of this talk will be the remnants of these partial orders on the orbits of the coadjoint action on their Lie algebras.

Myeonggi Kwon (Gießen) A computation of the ring structure in wrapped Floer homology

We describe an explicit computation of the ring structure on wrapped Floer homology of some real Lagrangians in Ak type Milnor fibers. The main ingredient is to use an isomorphism in v-shaped wrapped Floer homology inspired by the Seidel representation in Hamiltonian Floer homology. This talk is based on joint work with Hanwool Bae.
