Symplectic four-manifolds through branched coverings May 14 to May 18, 2018 American Institute of Mathematics, San Jose, CA Organizers: Tye Lidman, Daniel Ruberman, and Laura Starkston Description: This workshop, sponsored by AIM and the NSF, will be devoted to studying problems in the topology of symplectic four-manifolds by using connections with gauge theory, holomorphic curves, and algebraic geometry. The focus will be on concretely building connections between these areas and symplectic topology while working directly on specific problems in symplectic topology posed throughout the workshop. Deadline: November 14, 2017 Details: http://aimath.org/workshops/upcoming/symplecticfour
