HTL - Homology theories in low dimensional topology

Knot Floer homology is an invariant for knots and links defined by Ozsv\'ath and Szab\'o and independently by Rasmussen. It has proven to be a powerful invariant e.g. in computing the genus of a knot, or determining whether a knot is fibered. In this talk I define a generalisation of knot Floer homology for tangles; Tangle Floer homology is an invariant of tangles in D3, $S2xI or in S3. Tangle Floer homology satisfies a gluing theorem and its version in S3 gives back a stabilisation of knot Floer homology. Finally, I will discuss how to see tangle Floer homology as a categorification of the Reshetikhin-Turaev invariant for gl(1|1).

This is a joint work with I. Petkova and A. P. Ellis.
