通过引入参数λ(1-q/p<λ≤2,p≥q>1)及两个非负且在(0, ∞)递增的可微函数u(x)和v(x)建立了一种广义带权的Hardy-Hilbert积分不等式.特别,当p=2时,得到经典Hilbert积分不等式的各种推广.作为应用,当u(x)和v(x)是幂函数、指数函数和对数函数时,建立了若干重要不等式. 相似文献

Some new generalizations of the Hilbert integral inequality by introducing real functions ?(x) and ψ(x). The results of this paper reduce to those of the corresponding inequalities proved by Gao [Mingzhe Gao, On Hilbert's integral inequality, Math. Appl. 11 (3) (1998) 32-35]. Some applications are considered. 相似文献

§ 1 IntroductionAs well-known thatthe theory of Gronwall-Bellman type integral inequalities,both inone and more than one variable,is crucial and indispensable in the development of almostall kinds of analytic equations such as differential and integral equations,integro-differen-tial equations,functional-differential equations and evolution equations.However,only afew investigation works appreared so far in the literature which dealt with Gronwall typeinequalities involving improper integra… 相似文献

Some new inequalities of Hermite-Hadamard's integration are established.As for as inequalities about the righthand side of the classical Hermite-Hadamard's integral inequality refined by S Qaisar in [3],a new upper bound is given.Under special conditions,the bound is smaller than that in [3]. 相似文献

Some new weakly singular integral inequalities of Gronwall-Bellman type are established, which generalized some known weakly singular inequalities and can be used in the analysis of various problems in the theory of certain classes of differential equations, integral equations and evolution equations. Some applications to fractional differential and integral equations are also indicated. 相似文献
