Аннотация:
Knot concordance group is one of the fundamental objects in the study of knot theory and low-dimensional topology, and recently, the invariants obtained from different knot Floer homology theories proved to be very effective in studying and understanding the structure of this group. In this talk, I will describe the method that allows us to compute the concordance invariant epsilon using combinatorial knot Floer homology and talk about some computational results. This is a joint work with S. Dey.
