A nonmonotone trust-region-approach with nonmonotone adaptive radius for solving nonlinear systems [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2016 This paper presents a trust-region procedure for solving systems of nonlinear equations. The proposed approach takes advantages of an effective adaptive trust-region radius and a nonmonotone strategy by combining both of them appropriately.

Local convergence of Newton's method using Kantorovich convex majorants
Journal of Numerical Analysis and Approximation Theory, 2010 We are concerned with the problem of approximating a solution of an operator equation using Newton's method. Recently in the elegant work by Ferreira and Svaiter [6] a semilocal convergence analysis was provided which makes clear the relationship of the

Advanced Engineering Materials, EarlyView.This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Local Convergence of Newton’s Method on Lie Groups and Uniqueness Balls
Abstract and Applied Analysis, 2013 An estimation of uniqueness ball of a zero point of a mapping on Lie group is established. Furthermore, we obtain a unified estimation of radius of convergence ball of Newton’s method on Lie groups under a generalized L-average Lipschitz condition.

Weak convergence and the Prokhorov radius
Journal of Mathematical Analysis and Applications, 1992 The Prokhorov radius \(D(a,b,t,s)\) is defined as the supremum of the Prokhorov (Ky Fan) distance \[ d(X,a)=\inf\{r>0,\;\text{Pr}(| X- a|>r)
