## How many steps still left to x*?

Abstract The high speed of \(x_{k}\rightarrow x^\ast\in{\mathbb R}\) is usually measured using the C-, Q- or R-orders: \begin{equation}\tag{$C$} \lim \frac…

Abstract Let \(x_k\rightarrow x^\ast\in{\mathbb R}^N\); denote the errors by \( e_k: = \|x^\ast – x_k\| \) and the quotient factors…

AbstractThe process of diffusion in a random velocity field is the mathematical object underlying currently used stochastic models of transport in…
