DESCRIPTION:Title: Random dot products and roots of random polynomials\nAbs
 tract:\nPick your favorite two vectors $\vec{u}\, \vec{v} \in \mathbb{R}^n
 $\, and let $X$ be the dot product of $\vec{u}$ with a random permutation 
 of $\vec{v}$. What can be said about $\mathbb{P}(X=0)$? In this talk\, we 
 discuss this and related problems\, and we provide various upper bounds on
  this probability. As a motivating application\, throughout the talk\, we 
 will discuss the connections between this and the study of random polynomi
 als\, and we obtain new upper estimates on the expected number of critical
  points a random polynomial will have. This is a joint work with Aaron Ber
 ger\, Ross Berkowitz\, and Van Vu.
