A Posteriori Estimation of Dimension Reduction Errors [PDF]
, 2004 A new a posteriori error estimator is presented for the verification of the dimensionally reduced models stemming from the elliptic problems on thin domains. The original problem is considered in a general setting, without any specific assumptions on the domain geometry, coefficients and the right-hand sides.

Selecciones Matemáticas, 2023 The duality theory of convex analysis is applied to the complete electrode model (CEM), which is a standard model in electrical impedance tomography (EIT). This results in a dual formulation of the CEM and a general error estimate.

A posteriori error estimator and error control for contact problems [PDF]
Mathematics of Computation, 2009 In this paper, we consider two error estimators for one-body contact problems. The first error estimator is defined in terms of H ( div

A Posteriori Error Estimates for a Semidiscrete Parabolic Integrodifferential Control on Multimeshes
Discrete Dynamics in Nature and Society, 2012 We extend the existing techniques to study semidiscrete adaptive finite element approximation schemes for a constrained optimal control problem governed by parabolic integrodifferential equations.

A Posteriori Error Estimates for Pressure-Correction Schemes [PDF]
SIAM Journal on Numerical Analysis, 2016 Summary: A posteriori error estimates for time discretization of the incompressible Stokes equations by pressure-correction methods are presented. We rigorously prove global upper bounds for the incremental backward Euler scheme as well as for the two-step backward differential formula method (BDF2) in rotational form.
