Special Lectures in Analysis/Number Theory

A Zero-Density Approach to Smooth Numbers
Adam Harper
2:30pm|West Bldg. Lecture Hall

A number is said to be $y$-smooth if all of its prime factors are less than $y$. Such numbers appear in many places throughout analytic and combinatorial number theory, and much work has been done to investigate their distribution. I will try to...

Norm Convergence of Nonconventional Ergodic Averages
Miguel Walsh
1:30pm|West Bldg. Lecture Hall

Consider a group of measure preserving transformations acting on a probability space. The limiting behavior of the nonconventional ergodic averages associated with this action has been the subject of much attention since the work of Furstenberg on...

Partial Regularity of Solutions to the Navier-Stokes Equations in High Dimensions
3:15pm|S-101

I will discuss some recent results on partial regularity of solutions to the 4D non-stationary Navier-Stokes equations and the 6D stationary Navier-Stokes equations.

Rigidity of Actions on CAT(0) Cube Complexes
2:00pm|S-101

We illustrate how bounded cohomology with coefficients can be used to prove rigidity theorems for groups acting on non-positively curved spaces, among which CAT(0) cube complexes.
