open access: yesMathematika, Volume 63, Issue 3, Page 797-817, 2017., 2017
Let denote the number of integral solutions of the modified Vinogradov system of equations with . By exploiting sharp estimates for an auxiliary mean value, we obtain bounds for for . In particular, when satisfy and , we establish the essentially diagonal behaviour .
