1 本单元重、难点分析1)重点 :不等式的解的概念与解不等式的意义与方法是本单元的重点 .解不等式 ,就是将原来不简单的不等式 ,转换为与它同解的最简不等式 .这里所说的转换就是同解变形 .但中学里提到的不等式同解定理 ,对于解分式不等式和超越不等式就显得无能为力 .于是在不等式的解法中 ,常用“等价变形”的思想解决问题 .变形的途径常为 :含绝对值符号的不等式转换为去掉绝对值符号的不等式 ;分式不等式转换为整式不等式 ;无理不等式转换为有理不等式 ;高次不等式转换为低次不等式 ;超越不等式转换为整式不等式 .如何实施等价变形也… 相似文献

In this paper, we establish several new Hilbert-type inequalities with a homogeneous kernel, involving arithmetic, geometric, and harmonic mean operators in both integral and discrete case. Such inequalities are derived by virtue of some recent results regarding general Hilbert-type inequalities and some well-known classical inequalities. We also prove that the constant factors appearing in established inequalities are the best possible. As an application, we consider some particular settings and compare our results with previously known from the literature. 相似文献

The goal of this paper is to establish the relations between general Bernstein and Nikol’ski type inequalities under some weak conditions. From these relations some known classical inequalities are implied. Also, a family of functions equipped with Bernstein type inequality which satisfies Nikol’ski type inequality is found. 相似文献

In this paper, we consider Carlson type inequalities and discuss their possible improvement. First, we obtain two different types of generalizations of discrete Carlson's inequality by using the Hlder inequality and the method of real analysis, then we combine the obtained results with a summation formula of infinite series and some Mathieu type inequalities to establish some improvements of discrete Carlson's inequality and some Carlson type inequalities which are equivalent to the Mathieu type inequalities. Finally, we prove an integral inequality that enables us to deduce an improvement of the Nagy-Hardy-Carlson inequality. 相似文献

In this paper, some new Hardy-type inequalities involving many functions are obtained. These on the one hand generalize and on the other hand improve some existing results by Isumi and Isumi, Levinson, and Pachpatte on this famous type of inequalities. 相似文献
