A flexibility result in high-dimensional contact topology
If you have a question about this talk, please contact Ivan Smith.
Stein manifolds which admit a plurisubharmonic Morse function with no top index critical points are known to be flexible (their symplectic properties are essentially topological, governed by an h-principle). Recently, Emmy Murphy has shown that a Legendrian submanifold becomes flexible after an operation called stabilization, and its behavior is again governed by topology. The result I will be talking about shows that a local modification of the contact structure on the level set of a plurisubharmonic function renders all Legendrian submanifolds flexible. In particular this will allow us to take a symplectically non- trivial Stein cobordism, modify it locally to untangle all handle attachments, and render it trivial.
The talk reports on joint work with E. Murphy, O.Plamenevskaya, and A. Stipsicz.
