The Role of Convexity in Saddle-Point Dynamics: Lyapunov Function and Robustness [PDF]

open access: yesIEEE Transactions on Automatic Control, 2016
This paper studies the projected saddle-point dynamics associated to a convex–concave function, which we term saddle function. The dynamics consists of gradient descent of the saddle function in variables corresponding to convexity and (projected ...

Monotonicity, convexity, and inequalities for the generalized elliptic integrals

open access: yesJournal of Inequalities and Applications, 2017
We provide the monotonicity and convexity properties and sharp bounds for the generalized elliptic integrals K a ( r ) $\mathscr{K}_{a}(r)$ and E a ( r ) $\mathscr {E}_{a}(r)$ depending on a parameter a ∈ ( 0 , 1 ) $a\in(0,1)$ , which contains an earlier

Infinitesimal Convexity Implies Local Convexity [PDF]

open access: yesIndiana University Mathematics Journal, 1974
(the tangent space at p) such that expU has no points of M onthe \inside" of L. By the inside of Lwe mean the component of a tubularneighbor hood with Ldeleted which corresponds to the negative multiplesof the orienting normal vector eld under exp. The exponential maps arethose of M.It is an immediate consequence of one of the standard interpretations ...

Some trace inequalities for exponential and logarithmic functions [PDF]

open access: yesBulletin of Mathematical Sciences, 2019
Consider a function F(X,Y ) of pairs of positive matrices with values in the positive matrices such that whenever X and Y commute F(X,Y ) = XpYq. Our first main result gives conditions on F such that Tr[X log(F(Z,Y ))] ≤Tr[X(p log X + q log Y )] for all ...

The G-Convexity and the G-Centroids of Composite Graphs

open access: yesMathematics, 2020
The graph centroids defined through a topological property of a graph called g-convexity found its application in various fields. They have classified under the “facility location” problem.

A characterization of convex φ-functions [PDF]

open access: yesOpuscula Mathematica, 2012
The properties of four elements \((LPFE)\) and \((UPFE)\), introduced by Isac and Persson, have been recently examined in Hilbert spaces, \(L^p\)-spaces and modular spaces. In this paper we prove a new theorem showing that a modular of form \(\rho_{\Phi}(

Convexity in stochastic cooperative situations [PDF]

open access: yes, 2005
This paper introduces a new model concerning cooperative situations in which the payoffs are modeled by random variables. We analyze these situations by means of cooperative games with random payoffs. Special attention is paid to three types of convexity,

Schur m-power convexity of generalized geometric Bonferroni mean involving three parameters

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we study the Schur m-power convexity of the generalized geometric Bonferroni mean involving three parameters. Our result provides a unified generalization to the work that was done recently by Shi and Wu concerning the Schur convexity of ...

Nonlinear Operators as Concerns Convex Programming and Applied to Signal Processing

open access: yesMathematics, 2019
Splitting methods have received a lot of attention lately because many nonlinear problems that arise in the areas used, such as signal processing and image restoration, are modeled in mathematics as a nonlinear equation, and this operator is decomposed ...

On interval number in cycle convexity [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
Recently, Araujo et al. [Manuscript in preparation, 2017] introduced the notion of Cycle Convexity of graphs. In their seminal work, they studied the graph convexity parameter called hull number for this new graph convexity they proposed, and they ...
