Abstract
Our previous theorems on exponential sums often did not apply or did not give sharp results when certain powers of a variable appearing in the polynomial were divisible by p. We remedy that defect in this paper by systematically applying ppower reduction, making it possible to strengthen and extend our earlier results.
