*Title:* A Combinatorial Description of the Knot Concordance Invariant
Epsilon

*Abstract: *The knot concordance group is one of the central objects in the
study of topological knot types and low-dimensional topology. Concordance
invariants obtained from knot Floer homology have resulted in some
important classification results. In this talk, I will describe a new
method to compute the concordance invariant epsilon using combinatorial
knot Floer homology and show the computations for torus knots and positive
braids. This is a joint work with S. Dey.


See you Thursday!

Best,

Matt
