Hilbert-Kamke problem

The problem of the compatibility of a system of Diophantine equations of Waring type: \begin{equation}\label{eq:1} \left.{ \begin{array}{rcl} x_1^n + \cdots + x_s^n &=& N_n \\\ x_1^{n-1} + \cdots + x_s^{n-1} &=& N_{n-1} \\\ \ldots&&\\\ x_1 + \cdots + x_s &=& N_1 \end{array} }\right\rbrace \end{equation}

where the $x_1,\ldots,x_s$ assume integral non-negative values, certain additional restrictions [3] are imposed on the numbers $N_n,\ldots,N_1$, and $s$ is a sufficiently-large number which depends only on the natural number $4n$ which is given in advance.

The Hilbert–Kamke problem, which was posed in 1900 by D. Hilbert [1], was solved by E. Kamke, who proved that solutions to \eqref{eq:1} in fact exist. K.K. Mardzhanishvili in 1937 [3] obtained an asymptotic formula for the number of solutions of this system using the Vinogradov method for estimating trigonometric sums.
