Abstract
Knot Floer homology is an invariant for knots and links defined by Ozsvath and Szabo 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 pairing theorem and its version in S3 gives back a stabilisation of knot Floer homology. The talk will assume some interest, but little or no background in these topics.
This is a joint work with Ina Petkova.
