Exponential convexity and total positivity

open access: yesSibirskie Elektronnye Matematicheskie Izvestiya, 2020
Let \(I\) be one of the intervals \((0,\infty)\) and \((-\infty,\infty)\) and let \(f:I\rightarrow\mathbb{R}\) be a function associated to a continuous weight \(p:(a,b)\rightarrow\mathbb{R}_{+}\) via the formula \(f(x)=\int_{a}^{b}e^{xt}p(t)\mathrm{d}t.\) The main result of the paper under review is Theorem 2, that asserts that the kernel \(K(x,y)=f(x ...

An Exponentiality Test of Fit Based on a Tail Characterization against Heavy and Light-Tailed Alternatives

open access: yesRisks, 2023
Log-concavity and log-convexity play a key role in various scientific fields, especially in those where the distinction between exponential and non-exponential distributions is necessary for inferential purposes.

Sample-Based High-Dimensional Convexity Testing [PDF]

open access: yes, 2017
In the problem of high-dimensional convexity testing, there is an unknown set S in the n-dimensional Euclidean space which is promised to be either convex or c-far from every convex body with respect to the standard multivariate normal distribution.

Some Generalizations of the Jensen-Type Inequalities with Applications

open access: yesAxioms, 2022
Motivated by some results about reverses of the Jensen inequality for positive measure, in this paper we give generalizations of those results for real Stieltjes measure dλ which is not necessarily positive using several Green functions.

On k-Convex Polygons [PDF]

open access: yes, 2010
We introduce a notion of $k$-convexity and explore polygons in the plane that have this property. Polygons which are \mbox{$k$-convex} can be triangulated with fast yet simple algorithms. However, recognizing them in general is a 3SUM-hard problem.

Petrovic’s ´ type inequality for exponentially convex functions and coordinated exponentially convex functions

open access: yesPunjab University Journal of Mathematics, 2021
: In this paper, we produce a novel framework of a subclass of convex functions that is exponentially convex functions. Moreover, it is observed that the new concept helps to build new inequalities of Petrovic’s ´ type by employing exponentially convex functions.

Exponentially Convex Functions on Hypercomplex Systems [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
A hypercomplex system (h.c.s.) L1(Q, m) is, roughly speaking, a space which is defined by a structure measure (c(A, B, r), (A, B ∈ ℬ(Q))), such space has been studied by Berezanskii and Krein. Our main result is to define the exponentially convex functions (e.c.f.) on (h.c.s.), and we will study their properties.

Certain exponential type $ m $-convexity inequalities for fractional integrals with exponential kernels

open access: yesAIMS Mathematics, 2022
<abstract><p>By applying exponential type $ m $-convexity, the Hölder inequality and the power mean inequality, this paper is devoted to conclude explicit bounds for the fractional integrals with exponential kernels inequalities, such as right-side Hadamard type, midpoint type, trapezoid type and Dragomir-Agarwal type inequalities.

GENERALIZED POTENTIAL INEQUALITY AND EXPONENTIAL CONVEXITY

open access: yesМатематички билтен/BULLETIN MATHÉMATIQUE DE LA SOCIÉTÉ DES MATHÉMATICIENS DE LA RÉPUBLIQUE MACÉDOINE, 2013
In this paper we generalize the potential inequality which was introduced in [6] and extended to the class of naturally defined convex functions in [1]. The generalization is achieved by replacing the 1st order Taylor expansion of a convex function in the proof of the potential inequality with the n-th order Taylor expansion of an (n + 1)-convex ...
