"Introduction to the work of Baker and DeMarco"

We give an overview of the following result of Baker--DeMarco: if $\varphi,  \psi \in\mathbb{C}(z)$ have infinitely many preperiodic points in common, then all of their preperiodic points are the same. We discuss the connection between this complex analytic statement and non-archimedean Berkovich spaces.

"Facts about finite algebras"

If an algebra A is finite, what can we say about the variety HSP(A)? We'll show that such varieties are locally finite, i.e. its members which are finitely generated are in fact finite. Further, if such a variety has any infinite subdirectly irreducible algebras, then in fact it has arbitrarily large finite ones as well.

"Short Ride in a Height Machine"

This talk is meant to be a quick introduction to the theory of height functions on projective varieties defined over number fields.  After describing the fundamental case of heights on projective space, we go into the basics of Weil's height machine.  For any projective variety, this gives a height function attached to each linear equivalence class of Cartier divisors (or each line bundle), satisfying a variety of pleasant functorial properties.

"Statistical properties of B-free numbers"

B-free numbers were introduced by Erdős as a generalization of squarefree integers. I will present some results about the statistical properties of B-free numbers and a dynamical systems naturally associated to them. In particular, I will discuss a central limit theorem resembling a result by J. Beck on irrational circle rotations. Joint work with M. Avdeeva and Ya.G. Sinai.
