Abstract
In this paper there is established an asymptotic formula for the number of simultaneous representations of two numbers as sums of an increasing number of terms involving a power function, i.e., an asymptotic (as n→∞) formula is found for the number of solutions in integers xi, 0 ≤ xi ≤ p, of the following system of diophantine equations:
. The analysis is carried out as in the proof of a local limit theorem of probability theory and involves estimates of Weyl sums.
