On knot Floer homology and satellite knots
I will discuss the knot Floer homology invariants introduced by Ozsvath-Szabo and Rasmussen and what is known about these invariants for satellite knots. Part of this talk will address recent results calculating the Floer homologies of Whitehead doubles of (2,2n+1) torus knots. These results are part of joint work with Philip Ording of Columbia University which aims to calculate the Floer homology of (1,1) satellite knots.
