Existence results for a class of (p,q) Laplacian systems

open access: yesNonlinear Analysis, 2010
. We establish the existence of a nontrivial solution for inhomogeneous quasilinear elliptic systems: −∆pu = λ a(x) u |u|γ−2 + α (α + β)–1 b(x) u |u|α−2 |v|β + f    in Ω, −∆qv = µ d(x) v |v|γ−2 + β (α + β)–1 b(x) |u|α v |v|β−2 + g    in Ω, (u,v) ∈ W01,p ...

Degenerate Elliptic Systems [PDF]

open access: yesRocky Mountain Journal of Mathematics, 2005
We solve the Riemann-Hilbert boundary value problem for a linearly elliptic system of two second order differential equations in a simply connected domain in the plane, which is degenerate on the whole boundary of the domain and reduced to a simple (canonical) form, whose characteristic equation has simple roots (to within low order terms).

on the fucik spectrum for elliptic systems [PDF]

open access: yesTopological Methods in Nonlinear Analysis, 2006
We propose an extension of the concept of Fucik spectrum to the case of coupled systems of two elliptic equations, we study its structure and some applications. We show that near a simple eigenvalue of the system, the Fucik spectrum consists (after a suitable reparametrization) of two (maybe coincident) 2-dimensional surfaces.

Elliptic systems and material interpenetration

open access: yesFunctiones et Approximatio Commentarii Mathematici, 2009
We classify the second order, linear, two by two systems for which the two fundamental theorems for planar harmonic mappings, the Rado'-Kneser-Choquet Theorem and the H. Lewy Theorem, hold. They are those which, up to a linear change of variable, can be written in diagonal form with the same operator on both diagonal blocks.

Noncooperative elliptic systems [PDF]

open access: yesZeitschrift für angewandte Mathematik und Physik, 2010
We show how monotonicity methods combined with infinite dimensional sandwich pairs can be used to solve very general systems of equations that are not semibounded.

Einstein-Type Elliptic Systems

open access: yesAnnales Henri Poincaré, 2022
In this paper we analyse semi-linear systems of partial differential equations which are motivated by the conformal formulation of the Einstein constraint equations coupled with realistic physical fields on asymptotically Euclidean (AE) manifolds. In particular, electromagnetic fields give rise to this kind of system.

Spectral duality in elliptic systems, six-dimensional gauge theories and topological strings [PDF]

open access: yes, 2016
A bstractWe consider Dotsenko-Fateev matrix models associated with compactified Calabi-Yau threefolds. They can be constructed with the help of explicit expressions for refined topological vertex, i.e.

What is the complexity of elliptic systems?

open access: yesJournal of Approximation Theory, 1985
This paper deals with the optimal solution of the Petrovsky-elliptic system lu = f, where l is of homogeneous order t and f (x) ∈ H (Ω).Of particular interest is the strength of finite element information (FEI) of degree k, as well as the quality of the finite element method (FEM) using this information.
