Geometry and Topology Seminar

From Foliations to Contact Structures

Jonathan Bowden

Thursday 10 May 12:00–13:00 in Carslaw 351.

Please join us for lunch after the talk.

Abstract: In the mid 90's Eliashberg and Thurston established a fundamental link between the more classical theory of (smooth!) foliations and that of contact topology in dimension 3, which, amongst other things, played an important role in Mrowka and Kronheimer’s proof of Property P Conjecture. Their theory gains its potency from the fact that Gabai gave a very general method for constructing (smooth) taut foliations on 3-manifolds given from non-trivial homology classes.

On the other hand most foliations that occur in nature via (pseudo)-Anosov flows, surgery, gluing, blows ups... are not smooth in general. This naturally motivates the need to apply Eliashberg and Thurston’s theory to foliations of lower regularity. In this talk I will report on how their theory generalises. Time permitting I will discuss some applications and related questions.
