ANALYTICITY AND THEOREMS OF LIOUVILLE AND PHRAGMÉN-LINDELÖF TYPE FOR GENERAL ELLIPTIC SYSTEMS OF DIFFERENTIAL EQUATIONS

Mathematics of the USSR-Sbornik, 1974
Certain theorems on the analyticity of solutions of elliptic equations are used to prove theorems on the behavior of solutions of general elliptic systems of differential equations in unbounded regions, analogous to the classical theorems of Liouville and Phragmen-Lindelof for harmonic functions. Theorems on the uniqueness of the solutions for elliptic

Representation of a solution of a generalized boundary problem for a system of differential equations, elliptic in the sense of Petrovskii [PDF]

Ukrainian Mathematical Journal, 1985
Es sei \(\Omega\) ein Gebiet aus \(R^ n\), das mit einer geschlossenen Fläche S der Klasse \(C^{\infty}\) begrenzt ist. Es seien D(\({\bar \Omega}\)) und D(S) die Räume der unendlich oft differenzierbaren Funktionen auf \({\bar \Omega}=\Omega \cup S\) und S.

Construction of a Preconditioner for General Elliptic Problems Using Riesz Map

International Journal of Computational Methods, 2021
The current work aspires to design and study the construction of an efficient preconditioner for linear symmetric systems in a Hilbert space setting. Compliantly to Josef Málek and Zdeněk Strakoš’s work [Preconditioning and the Conjugate Gradient Method ...

Elastic Cable-Connected Satellites System Under Several Influences of General Nature: Equations of Motion in Elliptical Orbit

Science & Technology Journal, 2021
In the present work, we have applied the analytical approach to obtain the equations of motion of a system of two cable connected artificial satellites under the effect of various perturbative forces of general nature. These perturbative forces are the earth’s shadow, solar radiation pressure, earth’s oblateness and the earth’s magnetic field.

Analysis of two-operator boundary-domain integral equations for variable-coefficient mixed BVP in 2D with general right-hand side

Journal of Integral Equations and Applications, 2021
The mixed (Dirichlet-Neumann) boundary value problem (BVP) for the linear second-order scalar elliptic differential equation with variable coefficients in a bounded two-dimensional domain is considered in this paper.

Harnack type estimates to non-linear elliptic systems in the plane

Proceedings of the Royal Society of Edinburgh: Section A Mathematics
We establish a weak local boundedness to Lane–Emden systems in two-dimensional domains involving general second-order elliptic operators in divergence form and arbitrary positive powers whose product equals 1.
