We obtain Midpoint and Trapezoid Rules for the Riemann-Stieltjes integral which engender a natural generalization of Hadamard's integral inequality. Error terms are then obtained for this Riemann-Stieltjes Trapezoid Rule and other related quadrature rules. 相似文献

建立了一个关于Riemann-Liouville分数次积分的恒等式,利用此恒等式,得到了一些函数为可微且s-凸映射的关于分数次积分的新Hermite-Hadamard型积分不等式,并且对于可微的s-凹函数也得到一些新的结果.文中的新结果推广了部分已有研究的结论.最后给出了一个应用实例. 相似文献

Using an integral identity for a once differentiable mapping, this paper establishes
Hadamard's integral inequalities for $s$-convex and $s$-concave mappings. In
particular, our results improve and extend some known ones in the literature. Finally,
these inequalities are applied to special means. 相似文献

本文主要研究一类F-矩阵的性质,这类矩阵包含对称半正定矩阵,完全非负矩阵,τ矩阵和M-矩阵为其子类。我们不仅对F-矩阵改进了Hdamard不等式,而且证明对此类矩阵Hadamard不等式成立等式的充要条件是它的每条对角线,除主对角线外,都含有零元。 相似文献

In this paper, based on Betti's reciprocal theorem, a set of boundary integral equations of thin plate with a crack is introduced. These boundary integral equations can be used to solve the bending fracture problem of thin plate. In the analysis process a higher-order singular integral equation will be induced. Using the concept of the Hadamard's principal value the higher-order singular integral can be solved conveniently. By this method we have found the analytical solution of a thin plate with a straight crack under pure bending load and indicated how to use the BEM to analyze the bending and fracture problem for thin plate with a straight crack. At the end of the paper some numerical examples are given. Numerical results show the accuracy and efficiency of the algorithms. 相似文献

This paper considers the integrability for the Jacobian of orientation-preserving forms in anisotropic Sobolev classes. The main result is a sufficient condition ensuring integrability of the Jacobian, which can be regarded as a refinement of the result of Iwaniec and Sbordone. 相似文献
