Theory of probability distributions
Khinchin's theorem on the factorization of distributions says that every probability distribution P admits (in the convolution semi-group of probability distributions) a factorization where P1 is a probability distribution without any indecomposable factor and P2 is a distribution that is either degenerate or is representable as the convolution of a finite or countable set of indecomposable distributions. The factorization is not unique, in general. The theorem was proved by A. Ya. Khinchin for distributions on the line, and later it became clear that it is valid for distributions on considerably more general groups. A broad class (see) of topological semi-groups is known, including the convolution semi-group of distributions on the line, in which factorization theorems analogous to Khinchin's theorem are valid.

Maxim Kontsevich - An Update on Algebraic Hypergeometric Series
Algebraic hypergeometric series in one variable were classified in 1989 by F. Beukers and G. Heckman, in terms of finite complex reflection groups. Recently, K. Penson observed that one of such series is a generating series of a probability density with compact support, given again by an a

Dimitris Koukoulopoulos: Approximating reals by rationals
Abstract: Given any irrational number α, Dirichlet proved that there are infinitely many reduced fractions a/q such that |α − a/q| ≤ 1/q^2. A natural question that arises is whether the fractions a/q can get even closer to α. For certain ”quadratic irrationals” such as α = √2 the answer is
