Exponential decay toward equilibrium via log convexity for a degenerate reaction-diffusion system [PDF]

open access: yesJournal of Differential Equations, 2021
. We consider a system of two reaction-diffusion equations coming out of reversible chemistry. When the reaction happens on the totality of the domain, it is known that exponential convergence to equilibrium holds.

Exponential convexity for majorization [PDF]

open access: yesJournal of Inequalities and Applications, 2012
In this article, we give more generalized results than in Anwar et al. (2010) and Latif and Pečarić (2010) in new direction by using second-order divided difference. We investigate the exponential convexity and logarithmic convexity for majorization type results by using class of continuous functions in linear functionals.

Geometric Properties and Hardy Spaces of Rabotnov Fractional Exponential Functions

open access: yesFractal and Fractional, 2023
The aim of this study is to investigate a certain sufficiency criterion for uniform convexity, strong starlikeness, and strong convexity of Rabtonov fractional exponential functions. We also study the starlikeness and convexity of order γ.

Positive Semidefinite Matrices, Exponential Convexity for Majorization, and Related Cauchy Means

open access: yesJournal of Inequalities and Applications, 2010
We prove positive semidefiniteness of matrices generated by differences deduced from majorization-type results which implies exponential convexity and log-convexity of these differences and also obtain Lyapunov's and Dresher's inequalities for these ...

Properties of modified Bessel functions and completely monotonic degrees of differences between exponential and trigamma functions [PDF]

open access: yes, 2014
In the paper, the author establishes inequalities, monotonicity, convexity, and unimodality for functions concerning the modified Bessel functions of the first kind and compute the completely monotonic degrees of differences between the exponential and ...

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.

Positivity of Integrals for Higher Order $\nabla-$Convex and Completely Monotonic Functions [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
We extend the definitions of $\nabla-$convex and completely monotonic functions for two variables. Some general identities of Popoviciu type integrals $\int P(y)f(y) dy$ and $\int \int P(y,z) f(y,z) dy   dz$ are deduced.

Exponential Convergence Towards Stationary States for the 1D Porous Medium Equation with Fractional Pressure [PDF]

open access: yes, 2014
We analyse the asymptotic behaviour of solutions to the one dimensional fractional version of the porous medium equation introduced by Caffarelli and V\'azquez, where the pressure is obtained as a Riesz potential associated to the density.

Region of Variability for Exponentially Convex Univalent Functions [PDF]

open access: yesComplex Analysis and Operator Theory, 2010
For $α\in\IC\setminus \{0\}$ let $\mathcal{E}(α)$ denote the class of all univalent functions $f$ in the unit disk $\mathbb{D}$ and is given by $f(z)=z+a_2z^2+a_3z^3+\cdots$, satisfying $$ {\rm Re\,} \left (1+ \frac{zf''(z)}{f'(z)}+αzf'(z)\right)>0 \quad {in ${\mathbb D}$}.

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.
