Knot invariants from contact homology

Lenny Ng   [email] (AIM / Stanford)

Abstract: I will describe a technique of constructing invariants of knots and other submanifolds through contact topology and holomorphic curves. The knot invariant can be described purely topologically, with no reference to contact geometry, and is fairly strong. In particular, it encodes the Alexander polynomial and is closely related to the A-polynomial.

The stochastic porous media equation: a survey of recent results

Primal Screens

Carl Pomerance (Dartmouth College)

Abstract: This is an expository lecture, suitable for a wide audience! Please encourage your students to attend!
Prime numbers, the very building blocks of the integers, remain an enigma. Yet we make progress in our quest to understand these very basic objects. This non-stressful talk will highlight recent progress and some of the many problems that are still unsolved. Refreshments will be served before the talk in the math lounge, third floor Altgeld Hall.
