研究混合方次的Waring-Goldbach问题,证明除了至多O(N^47/48+E)个例外,所有不超过Ⅳ的偶数均可表为素数的2,3,4,5次方之和.
Abstract In this paper, we are concerned with Waring-Goldbach problems for unlike powers. It is proved that with at most O(N^47/48+E) exceptions, all even positive integers up to N are expressible in the form p^22 + p^3 3 + p^44 + p^55.
