"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.

Patrick Naylor, Department of Pure Mathematics, University of Waterloo   "Almost (generically) free of Chevalley"   This week, we'll go through the gritty details of Chevalley's theorem. Along the way, we'll see Grothendieck's Generic Freeness Lemma, and get to review some facts about rings. We'll then use this to prove the Nullstellensatz.
