Quasi Semi and Pseudo Semi (p,E)-Convexity in Non-Linear Optimization Programming

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
The class of quasi semi -convex functions and pseudo semi -convex functions are presented in this paper by combining the class of -convex functions with the class of quasi semi -convex functions and pseudo semi -convex functions, respectively.

Schur-Convexity of Averages of Convex Functions [PDF]

open access: yesJournal of Inequalities and Applications, 2011
The object is to give an overview of the study of Schur-convexity of various means and functions and to contribute to the subject with some new results. First, Schur-convexity of the generalized integral and weighted integral quasi-arithmetic mean is studied.

Strongly convex functions, Moreau envelopes and the generic nature of convex functions with strong minimizers [PDF]

open access: yes, 2015
In this work, using Moreau envelopes, we define a complete metric for the set of proper lower semicontinuous convex functions. Under this metric, the convergence of each sequence of convex functions is epi-convergence.

On the singularities of convex functions [PDF]

open access: yesManuscripta Mathematica, 1992
Given a semi-convex functionu: ω⊂R n→R and an integerk≡[0,1,n], we show that the set ∑k defined by $$\Sigma ^k = \left\{ {x \in \Omega :dim\left( {\partial u\left( x \right)} \right) \geqslant k} \right\}$$ is countably ℋn-k i.e., it is ...

A convexity of functions on convex metric spaces of Takahashi and applications [PDF]

open access: yes, 2015
We quickly review and make some comments on the concept of convexity in metric spaces due to Takahashi. Then we introduce a concept of convex structure based convexity to functions on these spaces and refer to it as $W-$convexity.

On φ-convexity of convex functions

open access: yesLinear Algebra and its Applications, 1998
AbstractWe construct a non-trivial set φ of extended-real valued functions on Rn, containing all affine functions, such that an extended-real valued function f on Rn is convex if and only if it is φ-convex in the sense of Dolecki and Kurcyusz, i.e., the (pointwise) supremum of some subset of φ. Also, we prove a new sandwich theorem.
