I explain two ways to convert a word in the generators of Artin's… knots reidemeister moves braid group bridge position From Eric Samperton 27 plays 0 Date of creation 2/9/2021 12:00 AM

I give some examples, calculate the homology of a lens space, and introduce normal curves. We then introduce knots and discuss the… heegaard diagram heegaard splitting lens space normal curves knots From Eric Samperton 27 plays 0 Date of creation 2/4/2021 12:00 AM
