> Title: Knot Floer homology and the mapping cone formula
> Abstract: Heegaard Floer theory provides us with invariants for   
> 3-manifolds and knots. In this talk I'll introduce these invariants   
> and mention how they are related to each other. As an application,  
> we  will see that these invariants sometimes obstruct 3-manifolds  
> being  surgery on a knot. This talk should be accessible to any  
> graduate  student who has taken a class on algebraic topology.

> 11:30-13:00 Erman Çineli
> Title: Viro patchworking
> Abstract: Viro's patchworking method gives a way to construct real   
> nonsingular curves with prescribed topology. With this method, Viro   
> constructed (upto isotopy) all nonsingular, degree 7 curves in the   
> real projective plane. This was a break-through in the  
> classification  problem of real nonsingular plane curves. In this  
> talk, I will  introduce the method and give a sketch of its proof.
