Rotation Matrix of a Charged Symmetrical Body: One-Parameter Family of Solutions in Elementary Functions

Universe
Euler–Poisson equations of a charged symmetrical body in external constant and homogeneous electric and magnetic fields are deduced starting from the variational problem, where the body is considered as a system of charged point particles subject to ...

Variational problem, Lagrangian and $\mu$-conservation law of the generalized Rosenau-type equation [PDF]

AUT Journal of Mathematics and Computing
The goal of this article is to compute conservation law, Lagrangian and $\mu$-conservation law of the generalized Rosenau-type equation using the homotopy operator, the $\mu$-symmetry method and the variational problem method.

Characterization of LU-efficiency and saddle-point criteria for F-approximated multiobjective interval-valued variational problems

Results in Control and Optimization, 2021
This paper aims to find a solution of interval uncertainty to multiobjective variational problems. For this, we consider an interval-valued multiobjective variational problem.

Homogenization of some degenerate pseudoparabolic variational inequalities

, 2018
Multiscale analysis of a degenerate pseudoparabolic variational inequality, modelling the two-phase flow with dynamical capillary pressure in a perforated domain, is the main topic of this work.

Morse theory and the resonant Q-curvature problem [PDF]

, 2014
In this paper, we study the prescribed $Q$-curvature problem on closed four-dimensional Riemannian manifolds when the total integral of the $Q$-curvature is a positive integer multiple of the one of the four-dimensional round sphere.

ON OPTIMAL 2-D DOMAIN SEGMENTATION PROBLEM VIA PIECEWISE SMOOTH APPROXIMATION OF A SELECTIVE TARGET MAPPING

Journal of Optimization, Differential Equations and Their Applications, 2019
In this paper we propose a new technique for the solution of the image segmentation problem which is based on the concept of a piecewise smooth approximation of some target functional.

Multistep hybrid viscosity method for split monotone variational inclusion and fixed point problems in Hilbert spaces

AIMS Mathematics, 2020
In this paper, we present a multi-step hybrid iterative method. It is proven that under appropriate assumptions, the proposed iterative method converges strongly to a common element of fixed point of a finite family of nonexpansive mappings, the solution

Contingent derivatives and regularization for noncoercive inverse problems

, 2018
We study the inverse problem of parameter identification in non-coercive variational problems that commonly appear in applied models. We examine the differentiability of the set-valued parameter-to-solution map by using the first-order and the second ...
