Sum of short exponential sums with prime numbers

Firuz Rakhmonov

For sufficiently large integers $K$ , $x$ , $y$ , and $q$ satisfying $K \leq y < x$ , where $f (u) = α u^{n} + α_{n - 1} u^{n - 1} + \dots + α_{1} u$ is a polynomial of degree $n$ with real coeff…

On the ternary Estermann problem with almost proportional summands

Firuz Rakhmonov

For $n \geq 3$ , an asymptotic formula is derived for the number of representations of a sufficiently large natural number $N$ in the form $p_{1} + p_{2} + m^{n} = N$ , where $p_{1}$ , $p_{2}$ $-$ pr…

Waring's problem with almost proportional summands

Zarullo Rakhmonov, Firuz Rakhmonov

For $n \geq 3$ , an asymptotic formula is derived for the number of representations of a sufficiently large natural number $N$ as a sum of $r = 2^{n} + 1$ summands, each of which is a…
