    Topic: Coxeter groups and invariants of knots and links
    Abstract: The meridional rank conjecture of Cappell and Shaneson posits equality between an algebraic invariant and a geometric invariant of links in S^3. I will describe a diagram coloring technique - which amounts to finding a Coxeter quotient of the fundamental group of the link complement - by which we can establish the conjecture for infinite classes of links. As a corollary, we derive formulas for the bridge numbers for the links in question. This talk should check the *T* and *A* boxes in *TACO* and lightly flirt with *C*. Based on joint works with Blair, Baader, Misev.
