Title
The Length of an Arithmetic Progression Represented by a Binary Quadratic Form.
Abstract
In this paper we prove that if Q(x,y) = ax(2) + bxy + cy(2) is an integral binary quadratic form with a nonzero, nonsquare discriminant d and if Q represents an arithmetic progression {kn + l : n = 0, 1, ..., R - 1), where k and l are positive integers, then there are absolute constants C-1 > 0 and L-1 > 0 such that R < C(1)l(k(2)vertical bar d vertical bar)(L)(1). Moreover, we prove that every nonzero integral binary quadratic form represents a nontrivial 3-term arithmetic progression infinitely often.
