On the Scalar Measure of Non-Normality of Matrices – Dimension vs. Structure
AbstractThe aim of this paper is to analyze the relative importance of the dimension and the structure of the square matrices…
On some one-step implicit methods as dynamical systems
AbstractThe one-step implicit methods, the backward Euler being the most known, require the solution of a nonlinear equation at each…

Generalized random walk algorithm for the numerical modeling of complex diffusion processes
AbstractA generalized form of the random walk algorithm to simulate diffusion processes is introduced. Unlike the usual approach, at a…
On approximating the inverse of a matrix
Abstract In this note we deal with two problems: the first regards the efficiency in approximating the inverse of a…
On the convergence order of some Aitken-Steffensen type methods
Abstract In this note we make a comparative study of the convergence orders for the Steffensen, Aitken and Aitken-Steffensen methods.…
Aitken-Steffensen-type methods for nonsmooth functions (III)
Abstract We provide sufficient conditions for the convergence of the Steffensen method for solving the scalar equation \(f(x)=0\), without assuming…
