Convergence rates of nonlinear Stokes problems in homogenization

Boundary Value Problems, 2019
In this paper, we study the convergence rates of solutions in homogenization of nonlinear Stokes Dirichlet problems. The main difficulty of this work is twofold.

Mean square convergence rates for maximum quasi-likelihood estimator

Stochastic Systems, 2015
In this note we study the behavior of maximum quasilikelihood estimators (MQLEs) for a class of statistical models, in which only knowledge about the first two moments of the response variable is assumed.

Rate of convergence of Lawson’s algorithm [PDF]

Mathematics of Computation, 1972
The algorithm of Charles L. Lawson determines uniform approximations of functions as limits of weighted L 2 {L_2} approximations. Lawson noticed from experimental evidence that the algorithm seemed to converge linearly and convergence was related to a factor which was the ratio of the largest ...

A kind of univariate improved Shepard-Euler operators

Open Mathematics
In this paper, a kind of univariate Shepard-Euler operators is studied by combining the known Shepard operator with the generalized Taylor polynomial as the expansion in the Euler polynomials.

General Convergence Rates by the Delayed Sums Method

Axioms
In this study, we propose a delayed sums method to investigate the convergence rates of partial sums. This approach enables general and systematic treatment of the convergence behavior of partial sums, encompassing and extending classical results such as

Convergence Rates for Branching Processes

The Annals of Probability, 1976
Almost sure estimates of the rate of convergence for the supercritical Galton-Watson process are obtained, e.g. $W - W_n = o(m^{-n/q})$ a.s. if and only if $E(Z_1^p \mid Z_0 = 1) < \infty$, where $1 < p < 2, 1/p + 1/q = 1$. Extensions to the multitype and continuous time cases are outlined.
