Special Year 2015-16: Workshop on Flows, Foliations and Contact Structures

Eliashberg and Thurston proved that the tangent plane field of any C2 taut oriented foliation F≠S1×S2 can be C0 approximated by a pair of particularly nice smooth contact structures. Kazez and Roberts proved that the requirement that F be C2 can be...

Contact homology is a powerful invariant of contact manifolds introduced by Eliashberg--Givental--Hofer. The definition involves certain counts of pseudo-holomorphic curves, however these are usually only "virtual" counts since the moduli spaces of...

I will speak about a simple way to represent surfaces in the three-space by diagrams similar to rectangular diagrams of links. A set of moves will be given by which one can connect any two diagrams representing isotopic surfaces. By forbidding some...

An interesting aspect of the classification of symplectic fillings of Seifert fibered spaces is the appearance of complex and symplectic line arrangements in CP2. Line arrangements have been studied classically for decades and have intricate...
