Some Integral Inequalities Involving Metrics

Entropy, 2021
In this work, we establish some integral inequalities involving metrics. Moreover, some applications to partial metric spaces are given. Our results are extension of previous obtained metric inequalities in the discrete case.

Convex and exact games with non-transferable utility [PDF]

, 2010
We generalize exactness to games with non-transferable utility (NTU). A game is exact if for each coalition there is a core allocation on the boundary of its payoff set. Convex games with transferable utility are well-known to be exact.

Triangulability of convex graphs and convex skewness [PDF]

Discrete Mathematics, Algorithms and Applications, 2021
Suppose [Formula: see text] is a subgraph of a convex complete graph [Formula: see text] and [Formula: see text] contains no boundary edge of [Formula: see text] and [Formula: see text]. We determine necessary and sufficient conditions on [Formula: see text] such that [Formula: see text] admits a triangulation.

Non-Linear Inner Structure of Topological Vector Spaces

Mathematics, 2021
Inner structure appeared in the literature of topological vector spaces as a tool to characterize the extremal structure of convex sets. For instance, in recent years, inner structure has been used to provide a solution to The Faceless Problem and to ...

Coxeter group in Hilbert geometry [PDF]

, 2015
A theorem of Tits - Vinberg allows to build an action of a Coxeter group $\Gamma$ on a properly convex open set $\Omega$ of the real projective space, thanks to the data $P$ of a polytope and reflection across its facets.

Hermite-Hadamard type inequalities in the setting of k-fractional calculus theory with applications

AIMS Mathematics, 2020
The main objective of this paper is to derive some new k-fractional refinements of HermiteHadamard like inequalities. We also discuss some new special cases of the main results.

Characterization of tropical hemispaces by (P,R)-decompositions [PDF]

, 2013
We consider tropical hemispaces, defined as tropically convex sets whose complements are also tropically convex, and tropical semispaces, defined as maximal tropically convex sets not containing a given point.

Ball and Spindle Convexity with respect to a Convex Body [PDF]

, 2012
Let $C\subset {\mathbb R}^n$ be a convex body. We introduce two notions of convexity associated to C. A set $K$ is $C$-ball convex if it is the intersection of translates of $C$, or it is either $\emptyset$, or ${\mathbb R}^n$.
