Abstract
For an element r of a ring R, a D(r) m-tuple is an m-tuple (a_1,\ldots ,a_m) of elements of R such that for all i,j with i\neq j, a_ia_j+r is a perfect square in R. In this article, we compute and estimate the measures of the sets of D(r) m-tuples in the ring \mathbb {Z}_p of p-adic integers, as well as in its residue field \mathbb F _p.
