In this note, we prove some results of elementary fixed point theory for mappings defined in metric spaces satisfying conditions of weak commutativity. Suitable examples are proven as well.

In this paper, we prove a general common fixed point theorem for two pairs of weakly compatible self-mappings of a metric space satisfying a weak Meir-Keeler type contractive condition by using a class of implicit relations. In particular, our result

In this paper, we prove a further generalized refinement of the weighted arithmetic-geometric mean inequality. As application, we show a new refinement of the generalized classical Hölder’s inequality and we give refinements to several inequalitie

In this paper, by the arithmetic-geometric mean inequality, we give a new generalization of refined Young?s inequality. As applications we present some new generalizations of refinements of Young inequalities for the determinants, traces and p-norms

In this paper, we prove that if a, b > 0 and 0 ≤ v ≤ 1. Then for all positive integer m (1) - For v ∈ v ∈ [ 0 , 1 2 n ] v \in \left[ {0,{1 \over {{2^n}}}} \right] , we have ( a v b 1 - v ) m + ∑ k = 1 n 2 k - 1 v m ( b m - ( a b 2 k - 1 - 1

We establish some new refinements to the Hölder inequality. We then apply them to provide some refinements to the extended Euler’s gamma and beta functions. As another application of our results, we give a new proof of the equivalence between the

In this work, we give further refinements of one of the most important extensions to Young’s inequalities due to Alzer–Fonseca–Kovacec (Linear Multilinear Algebra 63(3):622–635, 2015). As applications, we show some related inequalities for op
