Recursive Trust-Region Methods for Multiscale Nonlinear Optimization
A class of trust-region methods is presented for solving unconstrained nonlinear and possibly nonconvex discretized optimization problems, like those arising in systems governed by...

A New Ghost Cell/Level Set Method for Moving Boundary Problems: Application to Tumor Growth
Abstract In this paper, we present a ghost cell/level set method for the evolution of interfaces whose normal velocity depend upon the solutions of linear and nonlinear quasi-stead...

Third-order family of methods in Banach spaces
Recently, Parida and Gupta [J. Comp. Appl. Math. 206 (2007), 873-877] used Rall’s recurrence relations approach (from 1961) to approximate roots of nonlinear equations, by develo...

Verified error bounds for multiple roots of systems of nonlinear equations
It is well known that it is an ill-posed problem to decide whether a function has a multiple root. Even for a univariate polynomial an arbitrary small perturbation of a polynomial ...

Invariant solutions of certain nonlinear evolution type equations with small parameters
The Fisher equation, which arises in the study of reaction diffusion waves in biology, does not display a high level of symmetry properties. Consequently, only travelling wave sol...
