Title: Relative Symplectic Caps, 4-Genus and Fibered Knots.
Speaker: Mr. Dheeraj Kulkarni
Date: 13 July 2012
Time: 11.00 am- 12.00 noon
Venue: Department of Mathematics, Lecture Hall 1

The $4$-genus of a knot is an important measure of complexity, related to the unknotting number. A fundamental result used to study the $4$-genus and related invariants of homology classes is the \emph{Thom Conjecture}, proved by Kronheimer-Mrowka, and its symplectic extension due to Ozsvath-Szabo, which say that \textit{closed} symplectic surfaces minimize genus.
