Factorization of linear elliptic boundary value problems in non-cylindrical domains [PDF]
We present a method of factorization for linear elliptic boundary value problems considered in non-cylindrical domains. We associate a control problem to the boundary value problem which regularizes it. The technique of change of variables is used to study this problem.

The paper deals with a stationary non-Newtonian flow of a viscous fluid in unbounded domains with cylindrical outlets to infinity. The viscosity is assumed to be smoothly dependent on the gradient of the velocity.

On the Exact Boundary Control for the Linear Klein-Gordon Equation in Non-cylindrical Domains
The purpose of this paper is to study an exact boundary controllability problem in noncylindrical domains for the linear Klein-Gordon equation. Here, we work near of the extension techniques presented By J.

The integral equation approach to kinematic dynamo theory and its application to dynamo experiments in cylindrical geometry [PDF]
The conventional magnetic induction equation that governs hydromagnetic dynamo action is transformed into an equivalent integral equation system. An advantage of this approach is that the computational domain is restricted to the region occupied by the ...

Logarithmic wave equations in non-cylindrical domains
This paper is devoted to studying a type of logarithmic wave equation in non-cylindrical domains. Firstly, by the penalty method, we prove the existence of weak solutions to such kind of equations. Secondly, different from the dissipative wave equation, the energy defined in this problem is not always positive.

Enhanced diffusion and non-Gaussian dynamics in driven magnetic nanoparticles
We investigate the out-of-equilibrium dynamics of paramagnetic colloidal nanoparticles driven above a triangular lattice of cylindrical ferromagnetic domains. We use an external precessing magnetic field to create a dynamic energy landscape which propels

Limiting absorption principle and perfectly matched layer method for Dirichlet Laplacians in quasi-cylindrical domains [PDF]
We establish a limiting absorption principle for Dirichlet Laplacians in quasi-cylindrical domains. Outside a bounded set these domains can be transformed onto a semi-cylinder by suitable diffeomorphisms.

About the Benjamin-Bona-Mahony Equation in Domains with Moving Boundary
In this article, we prove the existence of solutions for an hyperbolic equation known as the Benjamin-Bona-Mahony equation. Our study involves increasing, decreasing, and mixed non-cylindrical domains and for this analysis, our main tools are the change ...

General Fractional Vector Calculus
A generalization of fractional vector calculus (FVC) as a self-consistent mathematical theory is proposed to take into account a general form of non-locality in kernels of fractional vector differential and integral operators.
