TLDR
In this article, error bounds for Galerkin proper orthogonal decomposition (POD) methods for linear and certain non-linear parabolic systems are proved and the resulting error bounds depend on the number of POD basis functions and on the time discretization.
Abstract
In this work error estimates for Galerkin proper orthogonal decomposition (POD) methods for linear and certain non-linear parabolic systems are proved. The resulting error bounds depend on the number of POD basis functions and on the time discretization. Numerical examples are included.

A New Certified Hierarchical and Adaptive RB-ML-ROM Surrogate Model for Parametrized PDEs

TL;DR: In this paper , the authors present a surrogate modeling technique for efficient approximation of input-output maps governed by parametrized PDEs, where the model is hierarchical as it is built on a full order model, reduced order model (ROM), and machine learning (ML) model chain.

Stable model reduction for linear variational inequalities with parameter-dependent constraints

TL;DR: In this paper , the authors consider model reduction for linear variational inequalities with parameter-dependent constraints and study the stability of the reduced problem in the context of a dualized formulation of the constraints using Lagrange multipliers.

Galerkin Finite Element Methods for Parabolic Problems

Vidar Thomée
TL;DR: The standard Galerkin method is based on more general approximations of the elliptic problem as discussed by the authors, and is used to solve problems in algebraic systems at the time level.

Control of the Burgers equation by a reduced-order approach using proper orthogonal decomposition

TL;DR: POD is utilized to solve open-loop and closed-loop optimal control problems for the Burgers equation to comparison of POD-based algorithms with numerical results obtained from finite-element discretization of the optimality system.
