Suppose that A is a subset of {1,...,N} such that the difference between any two elements of A is never one less than a prime. We show that |A| = O(N exp(-c(log N)^{1/4})) for some absolute c>0. 
Difference sets and the irreducibles in function fields
Let A be a subset of the polynomials of degree less than N over a finite field 픽q. Let r be any nonzero element of 픽q. We show that if the difference set A−A does not contain elements of the form
On sets of polynomials whose difference set contains no squares
Let Fq[t] be the polynomial ring over the finite field Fq, and let GN be the subset of Fq[t] containing all polynomials of degree strictly less than N . Define D(N) to be the maximal cardinality of a
A quantitative bound on Furstenberg-S\'ark\"ozy patterns with shifted prime power common differences in primes
Let k > 1 be a fixed integer, and PN be the set of primes no more than N . We prove that if set A ⊂ PN contains no patterns p1, p1 + (p2 − 1), where p1, p2 are prime numbers, then |A| |PN | ≪ ( log
On improving a Schur-type theorem in shifted primes
We show that if N ≥ exp(exp(exp(k))), then any k-colouring of the primes that are less than N contains a monochromatic solution to p1 − p2 = p3 − 1.
Difference sets and Polynomials of prime variables
Let \psi(x) be a polynomial with rational coefficients. Suppose that \psi has the positive leading coefficient and zero constant term. Let A be a set of positive integers with the positive upper
Polynomials and Primes in Generalized Arithmetic Progressions
We provide upper bounds on the density of a symmetric generalized arithmetic progression lacking nonzero elements of the form h(n) for natural numbers n, or h(p) with p prime, for appropriate
# A 85 INTEGERS 16 ( 2016 ) INTERSECTIONS OF SETS OF DISTANCE
We isolate conditions on the relative asymptotic size of sets of natural numbers A,B that guarantee a nonempty intersection of the corresponding sets of distances. Such conditions apply to a large
Problems and Results on Intersective Sets
By intersective set we mean a set H ⊂ Z having the property that it intersects the difference set A − A of any dense subset A of the integers. By analogy between the integers and the ring of

Difference sets and shifted primes
We show that if A is a subset of {1, …, n} which has no pair of elements whose difference is equal to p − 1 with p a prime number, then the size of A is O(n(log log n)−c(log log log log log n)) for
On sets of natural numbers whose difference set contains no squares
We show that if a sequence s/ of natural numbers has no pair of elements whose difference is a positive square, then the density of J/ n{l,...,«} is O(l/log«) c »), cn->-oo. This improves previous

On measures of intersectivity
A set A of positive integers is called (difference) intersective, if A N ( B B ) # 0 whenever B has positive upper density. Here instead of upper density we might equally naturally write lower or
