Hermite–Hadamard–Fejér type inequalities for p-convex functions

open access: yesArab Journal of Mathematical Sciences, 2017
In this paper, firstly, Hermite–Hadamard–Fejér type inequalities for p-convex functions are built. Secondly, an integral identity and some Hermite–Hadamard–Fejér type integral inequalities for p-convex functions are obtained.

Convex Functions and Spacetime Geometry

open access: yes, 2001
Convexity and convex functions play an important role in theoretical physics. To initiate a study of the possible uses of convex functions in General Relativity, we discuss the consequences of a spacetime $(M,g_{\mu \nu})$ or an initial data set $(\Sigma,

Directed Discrete Midpoint Convexity [PDF]

open access: yesarXiv, 2020
For continuous functions, midpoint convexity characterizes convex functions. By considering discrete versions of midpoint convexity, several types of discrete convexities of functions, including integral convexity, L$^\natural$-convexity and global/local discrete midpoint convexity, have been studied.

Some concepts of generalized convex functions (I)

open access: yesJournal of Numerical Analysis and Approximation Theory, 2002
An extension of the concept of convex function is given in a very general framework provided by a set in which a general convexity for its subsets is defined.

On the Sublinear Convergence Rate of Multi-Block ADMM

open access: yes, 2015
The alternating direction method of multipliers (ADMM) is widely used in solving structured convex optimization problems. Despite of its success in practice, the convergence properties of the standard ADMM for minimizing the sum of $N$ $(N\geq 3)$ convex

A geometric approach to second-order differentiability of convex functions [PDF]

open access: yesarXiv, 2023
We show a new, elementary and geometric proof of the classical Alexandrov theorem about the second order differentiability of convex functions. We also show new proofs of recent results about Lusin approximation of convex functions and convex bodies by $C^{1,1}$ convex functions and convex bodies.

The Schur-convexity of the mean of a convex function

open access: yesApplied Mathematics Letters, 2009
AbstractThe Schur-convexity at the upper and lower limits of the integral for the mean of a convex function is researched. As applications, a form with a parameter of Stolarsky’s mean is obtained and a relevant double inequality that is an extension of a known inequality is established.

Mechanisms of Increasing Weld Depth during Temporal Power Modulation in High‐Power Laser Beam Welding

open access: yesAdvanced Engineering Materials, EarlyView.
Temporal power modulation increases weld depth in high‐power laser beam welding of dissimilar round bars by nearly 20% compared to same average continuously welded welding power. The mechanism of action also applies to sheet welding and depends on the inertia of keyhole depth for the modulated laser beam power.

Recent Progress on Integrally Convex Functions [PDF]

open access: yesarXiv, 2022
Integrally convex functions constitute a fundamental function class in discrete convex analysis, including M-convex functions, L-convex functions, and many others. This paper aims at a rather comprehensive survey of recent results on integrally convex functions with some new technical results.
