For any measure preserving system (X, , μ,T) and A ∈ with μ(A) > 0, we show that there exist infinitely many primes p such that (the same holds with p − 1 replaced by p + 1). Furthermore, we show the existence of the limit in L 2(μ) of the associated ergodic average over the primes. A key ingredient is a recent result of Green and Tao on the von Mangoldt function. A combinatorial consequence is that every subset of the integers with positive upper density contains an arithmetic progression of… 
Random differences in Szemerédi’s theorem and related results
We introduce a new, elementary method for studying random differences in arithmetic progressions and convergence phenomena along random sequences of integers. We apply our method to obtain
Integer part polynomial multiple recurrence along shifted primes
Following an approach presented by N. Frantzikinakis, B. Host and B. Kra, we show that the parameters in the multidimensional Szemer\'edi theorem for integer part polynomials have non-empty

AbstractIf $\vec q_1 ,...,\vec q_m $ : ℤ → ℤℓ are polynomials with zero constant terms and E ⊂ ℤℓ has positive upper Banach density, then we show that the set E ∩ (E − $\vec q_1 $ (p − 1)) ∩ … ∩ (E

Furstenberg Systems of Bounded Multiplicative Functions and Applications
We prove a structural result for measure preserving systems naturally associated with any finite collection of multiplicative functions that take values on the complex unit disc. We show that these
E-ergodicity and speedups
We introduce the notion of “E-ergodicity” of a measure-preserving dynamical system (where E is a subset of N). We show that given an E-ergodic system T and aperiodic system S, T can be sped up to

ASPECTS OF UNIFORMITY IN RECURRENCE
We analyze and cite applications of various, loosely related notions of uni- formity inherent to the phenomenon of (multiple) recurrence in ergodic theory. An assort- ment of results are obtained,

The primes contain arbitrarily long arithmetic progressions
We prove that there are arbitrarily long arithmetic progressions of primes. There are three major ingredients. The first is Szemeredi�s theorem, which asserts that any subset of the integers of
