Topology Seminar (Main Talk): Smooth and singular symplectic surfaces

Seminar | March 7 | 4-5 p.m. | 3 Evans Hall

 Laura Starkston, Stanford

 Department of Mathematics

We will discuss some problems and results about symplectic surfaces in 4-manifolds, particularly in the complex projective plane. The main question is to classify symplectic surfaces up to symplectic isotopy. If the surface has singularities, we restrict the isotopies to the class of surfaces with the same model singularities.
