Fréchet derivative for light-like Wilson loops

open access: yesPhysics Letters B, 2015
We address the equations of motion for the light-like QCD Wilson exponentials defined in the generalized loop space. We attribute an important class of the infinitesimal shape variations of the rectangular light-like Wilson loops to the Fréchet ...

Convergence of Halley's method under centered Lipschitz condition on the second Fréchet derivative

open access: yesJournal of Numerical Analysis and Approximation Theory, 2013
We present a semi-local as well as a local convergence analysis of Halley's method for approximating a locally unique solution of a nonlinear equation in a Banach space setting.

On higher-order adjacent derivative of perturbation map in parametric vector optimization

open access: yesJournal of Inequalities and Applications, 2016
This paper deals with higher-order sensitivity analysis in terms of the higher-order adjacent derivative for nonsmooth vector optimization. The relations between the higher-order adjacent derivative of the minima/the proper minima/the weak minima of a ...

The Fréchet Derivative of an Analytic Function of a Bounded Operator with Some Applications [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
The main result in this paper is the determination of the Fréchet derivative of an analytic function of a bounded operator, tangentially to the space of all bounded operators. Some applied problems from statistics and numerical analysis are included as a

Fréchet-Derivative-Based Global Sensitivity Analysis and Its Physical Meanings in Structural Design

open access: yesApplied Sciences
Sensitivity analysis is essential for uncertainty-based structural design and analysis, especially global sensitivity analysis, which can reflect the overall physical properties of large and complex computational models with stochastic parameters.

Cyclicity in families of circle maps [PDF]

open access: yes, 2013
In this paper we will study families of circle maps of the form x↦x+2πr+af(x)(mod2π) and investigate how many periodic trajectories maps from this family can have for a ‘typical’ function f provided the parameter a is ...

Computing the fréchet derivative of the matrix exponential, with an application to condition number estimation [PDF]

open access: yes, 2008
The matrix exponential is a much-studied matrix function having many applications. The Fréchet derivative of the matrix exponential describes the first-order sensitivity of eA to perturbations in A and its norm determines a condition number for eA. Among
