A Perturbed Milne’s Quadrature Rule for n-Times Differentiable Functions with Lp-Error Estimates
In this work, a perturbed Milne’s quadrature rule for n-times differentiable functions with Lp-error estimates is derived. One of the most important advantages of our result is that it is verified for p-variation and Lipschitz functions.

Fast rates for estimation error and oracle inequalities for model section [PDF]
We consider complexity penalization methods for model selection. These methods aim to choose a model to optimally trade off estimation and approximation errors by minimizing the sum of an empirical risk term and a complexity penalty.

Model Reduction of Parametric Differential-Algebraic Systems by Balanced Truncation
We deduce a procedure to apply balanced truncation to parameter-dependent differential-algebraic systems. For that we solve multiple projected Lyapunov equations for different parameter values to compute the Gramians that are required for the truncation ...

Reliable Eigenspace Error Estimation Using Source Error Estimators
Abstract We introduce a framework for repurposing error estimators for source problems to compute an estimator for the gap between eigenspaces and their discretizations. Of interest are eigenspaces of finite clusters of eigenvalues of unbounded nonselfadjoint linear operators with compact resolvent.

Mesh-Free MLS-Based Error-Recovery Technique for Finite Element Incompressible Elastic Computations
The finite element error and adaptive analysis are implemented in finite element procedures to increase the reliability of numerical analyses. In this paper, the mesh-free error-recovery technique based on moving least squares (MLS) interpolation is ...

Global error estimation of linear multistep methods through the Runge-Kutta methods [PDF]
In this paper, we study the global truncation error of the linear multistep methods (LMM) in terms of local truncation error of the corresponding Runge-Kutta schemes. The key idea is the representation of LMM with a corresponding Runge-Kutta method.
