摘要 首先讨论Benson方法的优点与缺点,然后对于涉及n次连续可微的函数u(x)使用简明的Benson程序建立相关的积分微分不等式.例如,我们有(下面定理3):假设v(x)是区间[a,b]上n阶连续可微函数,它的n阶导数v(n)(x)0,且Q(v(n-1),L,v,′v,x)和G(v(n-1),L,v,′v,x)对v(n-1)的偏导数Gv(n-1)均为连续可微的正值函数,那么,当0<v(n)[Q/Gv(n-1)]1/(α-1)<M(M 2)和下面积分存在时,成立本文中的不等式(6). First of all,we discuss that Benson's method has both strong and weak points. By means of "Benson's programming", then we establish the related integro-differential inequalities involving an ntimes continuously differentiable function u (x). For example, we have ( Theorem 3 ) : Let v (x) he an n -times continuously differentiable function on [a,b] with v^(n) (x) ≥0,let Q(v^(n-1) ]^1/(n-1) and G (v^(n-1) ,L,v',v,x) be continuously differentiable positive functions. If 0 〈 v^(n) [ Q/Gv(n-1)]^1/(n-1) 〈 M (M(≥2) ) and the integrals exit,then the inequalities (6) hold of this paper.
