DESCRIPTION:The classical degree-genus formula computes the genus of a non
 singular algebraic curve in the complex projective plane. The well-known T
 hom conjecture posits that this is a lower bound on the genus of smoothly 
 embedded\, oriented and connected surface in CP^2.  The conjecture was fir
 st proved twenty-five years ago by Kronheimer and Mrowka\, using Seiberg-W
 itten invariants.  In this talk\, we will describe a new proof of the conj
 ecture that combines contact geometry with the novel theory of bridge tris
 ections of knotted surfaces. Notably\, the proof completely avoids any gau
 ge theory or pseudoholomorphic curve techniques.
