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 ...

Inertial projection methods for solving general quasi-variational inequalities

open access: yesAIMS Mathematics, 2021
In this paper, we consider a new class of quasi-variational inequalities, which is called the general quasi-variational inequality. Using the projection operator technique, we establish the equivalence between the general quasi-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 ...

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.

Existence of solutions for a perturbed problem with logarithmic potential in $\mathbb{R}^2$

open access: yesMathematics in Engineering, 2020
We study a perturbed Schrödinger equation in the plane arising from the coupling of quantum physics with Newtonian gravitation. We obtain some existence results by means of a perturbation technique in Critical Point Theory.

VARIATIONAL METHODS IN IMAGE RECOVERY

open access: yesPesquimat, 2014
We study the semicuadratic minimization problem of the formthis functional arises in image recovery problems, when aimage that describe a real scene, consider like a function f: ΩR2 → R, is observed and reproduced like a function p: Ω R2 → R.

Combined effects for a class of fractional variational inequalities [PDF]

open access: yesOpuscula Mathematica
In this paper, we study the existence of a nonnegative weak solution to the following nonlocal variational inequality: \[\int_{\mathbb{R}^N}(-\Delta)^{\frac{s}{2}} u (-\Delta)^{{\frac{s}{2}}}(v-u)dx+\int_{\mathbb{R}^N}(1+\lambda M(x))u(v-u)dx \geq \int_{\

Penalty methods for a variational quantum eigensolver

open access: yesPhysical Review Research, 2021
The variational quantum eigensolver (VQE) is a promising algorithm to compute eigenstates and eigenenergies of a given quantum system that can be performed on a near-term quantum computer.
