Positive braids and concordance

These lecture notes discuss notions of positivity for braids and links, their relation to complex plane curves, and how they provide strong restrictions on concordance properties of knots; e.g., sliceness. The notes are based on a three-hour mini-course delivered at Winter Braids XII.

Abstract

These lecture notes discuss notions of positivity for braids and links, their relation to complex plane curves, and how they provide strong restrictions on concordance properties of knots; e.g., sliceness. The notes are based on a three-hour mini-course delivered at Winter Braids XII.
