NorCal Symplectic Seminar: Weinstein handlebodies for complements of smoothed toric divisorsSpecial Events
|Speaker:||Angela Wu, University College London|
|Start time:||Mon, Apr 5 2021, 1:00PM|
In this talk, we are concerned with two important classes of symplectic manifolds: toric manifolds, which are equipped with an effective Hamiltonian action of the torus, and Weinstein manifolds, which come with handle decompositions compatible with their symplectic structures. The complements of a class of smoothed toric divisors which we call "centered" support a Weinstein structure, thus can be fully described by Weinstein diagrams. I will show you an algorithm which produces the specific Weinstein handlebody diagram of such complements. This is based on joint work with Acu, Capovilla-Searle, Gadbled, Marinković, Murphy, and Starkston.
