On the existence of weak solutions for p,q-laplacian systems with weights

Electronic Journal of Differential Equations, 2008
This paper studies degenerate quasilinear elliptic systems involving p,q-superlinear and critical nonlinearities with singularities. Existence results are obtained by using properties of the best Hardy-Sobolev constant together with an approach ...

Bounded and large radially symmetric solutions for some (p,q)-Laplacian stationary systems

Electronic Journal of Differential Equations, 2012
This article concerns radially symmetric positive solutions of second-order quasilinear elliptic systems. In terms of the growth of the variable potential functions, we establish conditions such that the solutions are either bounded or blow up at ...

Three dimensional reductions of four-dimensional quasilinear systems

, 2017
International audienceIn this paper, we show that four-dimensional quasilinear systems of first order integrable by the method of two-dimensional hydrodynamic reductions possess infinitely many three-dimensional hydrodynamic reductions, which are also ...

Singular quasilinear elliptic systems in RN

, 2019
The existence of positive weak solutions to a singular quasilinear elliptic system in the whole space is established via suitable a priori estimates and Schauder's fixed point theorem.

Equivalent Nonlinearization Technique for Random Analysis of Nonlinear System With Fractional Derivative Damping

Shock and Vibration
Solving nonlinear systems with fractional derivative damping is often challenging, particularly in cases of strong damping and excitation. To derive solutions for such strong nonlinear systems more concisely, this manuscript presents an approximate ...

Existence of bounded solutions for quasilinear parabolic systems with quadratic growth

Electronic Journal of Differential Equations, 2016
Assuming the existence of an upper and a lower solution, we prove the existence of at least one bounded solution of a quasilinear parabolic systems, with nonlinear second member having a quadratic growth with respect to the gradient of the solution.

Existence of solutions for quasilinear elliptic degenerate systems with L^1 data and nonlinearity in the gradient

Electronic Journal of Differential Equations, 2013
In this article we show the existence of weak solutions for some quasilinear degenerate elliptic systems arising in modeling chemotaxis and angiogenesis.
