Symplectic trisections and the adjunction inequality Lambert-Cole, Peter


When I was a graduate student, Dave Gay asked me if I could find a way to "see" when a 4-manifold X admits a symplectic structure via a trisection of X. I've finally got the answer, but it took a surprising route to get there and required first understanding how to prove the adjunction inequality using trisections. In this talk, I will discuss the basics of symplectic trisections, their relation to the adjunction inequality and the minimal genus problem, as well as some potential applications.
