Meeting 3.1: More on knots, and building knot diagrams from braid words

We combinatorialize tame knots using stick presentations, then form knot diagrams by taking regular projections onto a plane. I explain two ways to convert a word in the generators of Artin's…

Meeting 2.2: More on Heegaard diagrams, knots and knot equivalence

We continue the discussion of Heegaard diagrams from last time. I give some examples, calculate the homology of a lens space, and introduce normal curves. We then introduce knots and discuss the…
