Weinstein Neighborhoods under HMS
Monday 24 March 2025
Speaker: Jeff Hicks (St. Andrews)
Location: J11
Time: 2.00pm
Abstract: The Weinstein neighborhood theorem states that every Lagrangian submanifold L of a symplectic manifold X has a symplectic neighborhood modeled on the cotangent bundle of L. A consequence of this is that, in some nice cases, we have a Viterbo restriction functor from the Fukaya category of X to the Fukaya category of T*L. In this talk, I'll discuss some parallels between this restriction functor and the restriction to an affine neighborhood of a point in an algebraic variety, and use this to provide a definition of a "noncommutative affine neighborhood" of an object in a triangulated category. We'll then construct a few examples of these noncommutative affine neighborhoods and discuss applications. While we will use some intuition from symplectic geometry in this talk, we won't use any symplectic techniques in our examples or computations.
