Title: A Poly-Time Knot Polynomial Via Solvable Approximation Abstract: I will construct the first poly-time-computable knot polynomial since Alexander's (1928) by using some new commutator-calculus techniques and a Lie algebra ${\mathfrak g}_1$ which is at the same time solvable and an approximation of the simple Lie algebra $sl_2$. Slides for the talk can be found at http://www.math.toronto.edu/drorbn/Talks/UNC-1610/.

Title: Dynamics of the energy critical wave equations Abstract: These lectures concern the energy-critical focusing nonlinear wave equation. It is conjectured that any solution of this equation that is bounded in the energy space is asymptotically the sum of a finite number of decoupled solitons and a radiation term. My goal is to prove this conjecture for radial solutions in space dimension 3 and to give partial results in the general case. This is based on joint works with Hao…
