An Extension of the Erdös-debrunner Inequality to General Power Means

چکیده

Given the harmonic mean μ of the numbers xi (i = 1, 2, 3) and a t ∈ (0,min{x1, x2, x3}/μ}), we determine the best power mean exponents p and q such that Mp(xi − tμ) ≤ (1 − t)μ ≤ Mq(xi − tμ), where p and q only depend on t. Also, for t > 0 we similarly handle the estimates Mp(xi + tμ) ≤ (1 + t)μ ≤Mq(xi + tμ).

A Proof of Two Conjectures Related to the Erdös-debrunner Inequality

In this paper we prove some results which imply two conjectures proposed by Janous on an extension to the p-th power-mean of the Erdös–Debrunner inequality relating the areas of the four sub-triangles formed by connecting three arbitrary points on the sides of a given triangle.

On the Extension of the Erdös–mordell Type Inequalities

We discuss the extension of inequality RA c a rb + b a rc to the plane of triangle ABC . Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdös-Mordell inequality, and some inequalities of Erdös-Mordell type. Mathematics subject classification (2010): 51M16, 51M04, 14H50.

General Hardy-Type Inequalities with Non-conjugate Exponents

We derive whole series of new integral inequalities of the Hardy-type, with non-conjugate exponents. First, we prove and discuss two equivalent general inequa-li-ties of such type, as well as their corresponding reverse inequalities. General results are then applied to special Hardy-type kernel and power weights. Also, some estimates of weight functions and constant factors are obtained. ...

Extension of Hardy Inequality on Weighted Sequence Spaces

Let and be a sequence with non-negative entries. If , denote by the infimum of those satisfying the following inequality: whenever . The purpose of this paper is to give an upper bound for the norm of operator T on weighted sequence spaces d(w,p) and lp(w) and also e(w,?). We considered this problem for certain matrix operators such as Norlund, Weighted mean, Ceasaro and Copson ma...
