On a class of punctual convex functions

open access: yes, 2014
The aim of this paper is to show that the inequality of Jensen for real functions holds under a weaker condition than the usual convexity on an interval. Thus, we introduce the concept of convexity at a point.

A new interpretation of Jensen's inequality and geometric properties of φ -means

open access: yesJournal of Inequalities and Applications, 2011
We introduce a mean of a real-valued measurable function f on a probability space induced by a strictly monotone function φ. Such a mean is called a φ-mean of f and written by Mφ (f).

A strong convergence theorem on solving common solutions for generalized equilibrium problems and fixed-point problems in Banach space

open access: yesFixed Point Theory and Applications, 2011
In this paper, the common solution problem (P1) of generalized equilibrium problems for a system of inverse-strongly monotone mappings and a system of bifunctions satisfying certain conditions, and the common fixed-point problem (P2) for a family of ...

Optimization problems with quasiconvex inequality constraints [PDF]

open access: yes
The constrained optimization problem min f(x), gj(x) 0 (j = 1, . . . , p) is considered, where f : X ! R and gj : X ! R are nonsmooth functions with domain X Rn.

Symmetric polynomials and $l^p$ inequalities for certain intervals of $p$

open access: yes, 2011
We prove some sufficient conditions implying $l^p$ inequalities of the form $||x||_p \leq ||y||_p$ for vectors $ x, y \in [0,\infty)^n$ and for $p$ in certain positive real intervals.
