N2 - For a prime p and integers a and b, we consider Salié sums S p(a, b) = ∑x=1
p-1χ2(x) exp(2πi(ax + bx̄)/p), where χ2(x) is a quadratic character and x̄ is the modular inversion of x, that is, xx̄ ≡ 1 (mod p). One can naturally associate with Sp(a, b) a certain angle p(a, b) ∈ [0, π]. We show that, for any fixed ε > 0, these angles are uniformly distributed in [0, π] when a and b run over arbitrary setsΑ, Β ⊆ {0,1,...,p -1} such that there are at least p1+ε quadratic residues modulo p among the products ab, where (a, b) ∈ Α× Β.
