Roth's theorem in the primes
We show that any set containing a positive proportion of the primes contains
a 3-term arithmetic progression. An important ingredient is a proof that the
primes enjoy the so-called Hardy-Littlewood majorant property. We derive this
by giving a new proof of a rather more general result of Bourgain which,
because of a close analogy with a classical argument of Tomas and Stein from
Euclidean harmonic analysis, might be called a restriction theorem for the
primes.Comment: 23 pages. Updated references and made some minor changes recommended

The Green-Tao theorem: an exposition
The celebrated Green-Tao theorem states that the prime numbers contain
arbitrarily long arithmetic progressions. We give an exposition of the proof,
incorporating several simplifications that have been discovered since the
original paper.Comment: 26 pages, 4 figure
