An asymptotic formula is obtained in generalized Estermann's ternary problem for noninteger powers with almost equal summands on the representations of a sufficiently large natural number as a sum of two primes and integer part of noninteger power of a natural number. Bibliography: 9 titles.
Keywords: exponential sums, Estermann's ternary problem with noninteger exponents, almost equal summands.
