Abstract

In this paper, we develop a method of evaluating general exponential sums with rational amplitude functions for multiple variables which complements works by T. Cochrane and Z. Zheng on the single variable case. As an application, for n≥ 2, a fixed natural number, we obtain an asymptotic formula for the (weighted) number of solutions of quadratic congruences of the form x₁²+x₂²+...+x_n²≡ x_n+1²\bmodp^m in small boxes, thus establishing an equidistribution result for these solutions.
