Gradient flow approach to an exponential thin film equation: global existence and latent singularity

open access: yes, 2018
In this work, we study a fourth order exponential equation, $u_t=\Delta e^{-\Delta u},$ derived from thin film growth on crystal surface in multiple space dimensions.

Jessen type functionals and exponential convexity

open access: yesJournal of Mathematics and Computer Science, 2017
Summary: In this paper, we introduce the extension of Jessen functional and investigate logarithmic and exponential convexity. We also give mean value theorems of Cauchy and Lagrange type. Several families of functions are also presented related to our main results.

Geometric Nature of the Turánian of Modified Bessel Function of the First Kind

open access: yesAxioms
This work explores the geometric properties of the Turanian of the modified Bessel function of the first kind (TMBF). Using the properties of the digamma function, we establish conditions under which the normalized TMBF satisfies starlikeness, convexity,

On Majorization for Matrices [PDF]

open access: yes, 2013
In this paper, we give several results for majorized matrices by using continuous convex function and Green function. We obtain mean value theorems for majorized matrices and also give corresponding Cauchy means, as well as prove that these means are ...

The Legendre Transform in Non-additive Thermodynamics and Complexity

open access: yes, 2017
We present an argument which purports to show that the use of the standard Legendre transform in non-additive Statistical Mechanics is not appropriate.

On the John–Nirenberg inequality

open access: yesJournal of Inequalities and Applications, 2020
We present a version of the John–Nirenberg inequality for a sub-class of BMO by estimating the corresponding mean oscillating distribution function via dyadic decomposition.

A Variational Perspective on Accelerated Methods in Optimization

open access: yes, 2016
Accelerated gradient methods play a central role in optimization, achieving optimal rates in many settings. While many generalizations and extensions of Nesterov's original acceleration method have been proposed, it is not yet clear what is the natural ...

Peierls–Bogolyubov’s Inequality for Deformed Exponentials

open access: yesEntropy, 2017
We study the convexity or concavity of certain trace functions for the deformed logarithmic and exponential functions, and in this way obtain new trace inequalities for deformed exponentials that may be considered as generalizations of Peierls–Bogolyubov’
