A note on variational methods [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1964
In this note a new development of the variational method due to G. M. Golusin will be given. The Golusin variational method, found in Geometrische Funktionentheorie [1, pp. 96-105], is established there only after rather lengthy and tedious considerations. Below, the interior variational formula of M. M.

Metric Methods in Calculus of Variations [PDF]

open access: bronzeProceedings of the National Academy of Sciences, 1937
1. In each problem of calculus of variations there are four fundamental data: (I) A point-space S or a domain of a point-space. (II) A function φ from which there is derived a functional in a class P of entities of S whose dimensions are ≧ 1. With each element C of & there is associated a number, say λ>φ,(C), by a process of integration of ϕ along C ...

Network element methods for linear elasticity

open access: yesComptes Rendus. Mécanique, 2023
We explain how to derive a network element for the linear elasticity problem. After presenting sufficient conditions on the network for the validity of a discrete Korn inequality, we also propose several variations of the presented method and in ...

On three-step iterative schemes associated with general quasi-variational inclusions

open access: yesAlexandria Engineering Journal, 2022
In this paper, we investigate new classes of general quasi-variational inclusions. In this regard, we prove that general quasi-variational inclusions and fixed point problems are equivalent.

The variational method of moments

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2023
Abstract The conditional moment problem is a powerful formulation for describing structural causal parameters in terms of observables, a prominent example being instrumental variable regression. We introduce a very general class of estimators called the variational method of moments (VMM), motivated by a variational minimax reformulation

Inexact Model: A Framework for Optimization and Variational Inequalities [PDF]

open access: yes, 2020
In this paper we propose a general algorithmic framework for first-order methods in optimization in a broad sense, including minimization problems, saddle-point problems and variational inequalities.

Improved variational methods in statistical data assimilation [PDF]

open access: yesNonlinear Processes in Geophysics, 2015
Data assimilation transfers information from an observed system to a physically based model system with state variables x(t). The observations are typically noisy, the model has errors, and the initial state x(t0) is uncertain: the data assimilation ...
