Mathematicians from around the country participated in a “Knot Concordance and Homology Cobordism” workshop July 19-23 at Wesleyan. In 1957, R. H. Fox and J. Milnor introduced the seminal idea that the concordance class of the link of a singularity obstructs its removal. Both concordance of knots, and the motivating goal of understanding singularities remain central to topology and algebraic geometry. The conference brought together a variety of researchers and students in geometric topology whose work connects to this fundamental idea.
