The first eigenvalue of -Laplacian systems with nonlinear boundary conditions

Boundary Value Problems, 2005
We study the properties of the positive principal eigenvalue and the corresponding eigenspaces of two quasilinear elliptic systems under nonlinear boundary conditions.

A subsolution-supersolution method for quasilinear systems

Electronic Journal of Differential Equations, 2005
Assuming that a system of quasilinear equations of gradient type admits a strict supersolution and a strict subsolution, we show that it also admits a positive solution.

Numerical methods for hyperbolic differential functional problems [PDF]

Opuscula Mathematica, 2008
The paper deals with the initial boundary value problem for quasilinear first order partial differential functional systems. A general class of difference methods for the problem is constructed. Theorems on the error estimate of approximate solutions for

Weakly Coupled Systems Of Quasilinear Hyperbolic Equations

, 1993
. We obtain some general comparison results for entropy solutions of weakly coupled systems of conservation laws with source. For some particular couplings, by using these comparison methods, we show the global existence of the solutions to the Cauchy ...

Quasilinear evolution equations and parabolic systems

, 1986
It is shown that general quasilinear parabolic systems possess unique maximal classical solutions for sufficiently smooth initial values, provided the boundary conditions are “time-independent”.

A qualitative study on the existence of positive solutions for local and nonlocal elliptic integro-differential quasilinear systems

Boundary Value Problems
In this work, we give a qualitative study on the existence of positive solutions for local and nonlocal elliptic integro-differential quasilinear systems, by using the concept of super- and subsolutions combined with Schauder’s fixed point theorem.
