摘要
研究正奇数n=p_(1)+p^(3)_(2)+p^(k)_(3)(k∈N且k≥4)的可表问题。运用堆垒素数论中的圆法,借助圆法中的迭代方法处理主区间,并利用指数和方法处理余区间,得到以下结论:对于给定的充分大的正整数N和任意实数ε>0,除O(N31/60+2/k-2/3k×2^(k-1)+ε)个例外,所有的正奇数n(n≤N)都可以表示为p_(1)+p^(3)_(2)+p^(k)_(3),其中p_(1)、p_(2)、p_(3)为素数。
The representability of positive odd number n=p_(1)+p^(3)_(2)+p^(k)_(3)(k∈N and k≥4)was studied.The circle method in additive number theory and the iterative method in the circle method were used to deal with the main arcs and the exponential sum method was used to deal with the minor arcs.The final conclusions were reached:Let N be a sufficiently large integer,then for anyε>0,it is proved that with at most O(N31/60+2/k-2/3k×2^(k-1)+ε)exceptions,all odd positive integers up to N can be represented in the form p_(1)+p^(3)_(2)+p^(k)_(3),where p_(1)、p_(2)、p_(3) are prime numbers.
