Metrics whose Ricci tensor vanishes are called Ricci-flat, and many interesting examples of these metrics arise in the Kahler setting. I will present some background of K3 surfaces, which give fundamental examples of Ricci-flat Kahler metrics.

I will present a result in combinatorial number theory due to Renling Jin: if A and B are subsets of the natural numbers with positive *Banach density*, then their sum A+B is *piecewise syndetic*, a robust notion of largeness for subsets of the natural numbers. The result bears a resemblance to a theorem of real analysis due to Steinhaus: if C and D are subsets of the real line with positive Lebesgue measure, then their sum C+D contains an interval. We will in fact see that these two theorems are both specific instances of a more general theorem using the language of *nonstandard analysis*.

We will discuss several examples of modeling with random media, in particular the case

of wave propagation through the tubulent atmosphere.

Zeta functions are central topics in number theory and arithmetic algebraic geometry.

They can be viewed as generating functions for counting "points" of polynomial equations.

In this lecture, we will explain various zeta functions from this point of view, including

the Riemann zeta function, the Hasse-Weil zeta function, and zeta functions over finite fields.

Let *X* be a finite collection of sets. Given *n*>*1* what is the maximal number of ways disjoint union of *n* sets (elements from *X*) is again a set in *X*? We will estimate this number in terms of n and the cardinality of X.
