Minimization of an M-convex function

open access: yesDiscrete Applied Mathematics, 1998
A function \(f : \mathbb{Z}^n \rightarrow \mathbb{R}\cup \{ \infty \}\) is called \(M\)-convex if for any two vectors \(x,y \in\mathbb{Z}^n\), such that \(f(x) , f(y) \neq \infty\), and any unit vector \(e_i\) in a direction where \(x - y\) is positive there is a unit vector \(e_j\) in a direction where \(x-y\) is negative, such that \(f(x) + f(y) \geq

M-Convex Function on Generalized Polymatroid [PDF]

open access: yesMathematics of Operations Research, 1999
The concept of M-convex function, introduced by Murota (1996), is a quantitative generalization of the set of integral points in an integral base polyhedron as well as an extension of valuated matroid of Dress and Wenzel (1990). In this paper, we extend this concept to functions on generalized polymatroids with a view to providing a unified framework ...

m-Convexity and Functional Equations [PDF]

open access: yesMoroccan Journal of Pure and Applied Analysis, 2017
AbstractIn this research we aim to explore some properties of m-convex functions from the point of view of functional equations or better, functional inequalities. So far studies of m- convexity have been devoted mainly to establish properties, inequalities and examples on the topic, but not to look at the problem from the perspective of functional ...

m-convex (m-cv) functions

open access: yesAzerbaijan Journal of Mathematics, 2023
Summary: The theory of \(m\)-convex \((m-cv)\) functions is a new direction in the theory of real geometry. However, for \(m=1\) this class coincides with the class of convex functions, and for \(m=n\) it coincides with the class of subharmonic functions, which, as is known, have been well studied (A. Aleksandrov, I. Bakelman, A.

The most important inequalities of $m$-convex functions [PDF]

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2017
The intention of this article is to investigate the most important inequalities of m-convex functions without using their derivatives. The article also provides a brief survey of general properties of m-convex functions.

Hermite–Hadamard type inequalities for m-convex and $( \alpha , m)$-convex functions [PDF]

open access: yesJournal of Inequalities and Applications, 2020
AbstractIn this paper, some new inequalities of the Hermite–Hadamard type for the classes of functions whose derivatives’ absolute values arem-convex and$( \alpha , m) $(α,m)-convex are obtained. The results obtained in this work extend and improve the corresponding ones in the literature.

Hadamard type inequalities for m–convex and (α, m)–convex functions via fractional integrals [PDF]

open access: yesAIP Conference Proceedings, 2018
In this paper, we established some new Hadamard-type integral inequalities for functions whose derivatives of absolute values are m-convex and (α,m)-convex functions via Riemann-Liouville fractional integrals.

A note on M-convex functions on jump systems

open access: yesDiscrete Applied Mathematics, 2021
A jump system is defined as a set of integer points (vectors) with a certain exchange property, generalizing the concepts of matroids, delta-matroids, and base polyhedra of integral polymatroids (or submodular systems). A discrete convexity concept is defined for functions on constant-parity jump systems and it has been used in graph theory and algebra.
