М. Виноградова. Здесь мы находим для $$n=r=2$$ оценки снизу показателей сходимости особого ряда и особого интеграла асимптотической формулы при $P\to\infty$для числа решений следующей системы диофантовых уравнений$$\sum_{j=1}^{2k}(-1)^jx_{1,j}^{t_1}\dots x_{r,j}^{t_r}=0,\quad 0\leq t_1,\dots, t_r\leq n,$$где $$n\geq 2,r\geq 1, k$$ - натуральные числа, причём каждая переменная $$x_{i,j}$$ может принимать все целые значения от 1 до $$P\geq 1.$$</p></abstract><trans-abstract xml:lang="en"><p>In the paper we continue studies on the theory of multivariate trigonometric sums, in the base of which lies of the I. M. Vinogradov's method. Here we obtain for $$n=r=2$$ lower estimates of the convergence exponent of the singular series and the singular integral of the asymptotic formulas for $$P\to\infty$$ for the number of solutions of the following system of Diophantine equations$$\sum_{j=1}^{2k}(-1)^jx_{1,j}^{t_1}\dots x_{r,j}^{t_r}=0,\quad 0\leq t_1,\dots, t_r\leq n,$$where $$n\geq 2,r\geq 1, k$$ are natural numbers, moreover an each variable $$x_{i,j}$$ can takeall integer values from 1 to $$P\geq 1.$$</p></trans-abstract><kwd-group xml:lang="ru"><kwd>показатель сходимости</kwd><kwd>особый интеграл</kwd><kwd>особый ряд</kwd></kwd-group><kwd-group xml:lang="en"><kwd>exponent of the convergence</kwd><kwd>singular integrals</kwd><kwd>singular series</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Виноградов И.М.
