On Entire Solutions for an Indefinite Quasilinear System of Mixed Power

چکیده
We prove non-existence and existence of entire positive solutions for a Schrödinger quasilinear elliptic system. To prove the non-existence, we combine a carefully-chosen test function with some results that we proved concerning the positivity of a kind of principal eigenvalue of a eigenvalue problem in RN with indefinite weights. Contrary to the existence, the non-existence results for this class of problems have not been studied very much in recent years. For the existence we mainly used upper and lower solution methods combined with comparison principles. Mathematics subject classification (2010): 35B08, 35B09, 35B53, 35J10, 35J57, 35J92.

Existence of Solutions for Quasilinear Elliptic Equations with Nonlinear Boundary Conditions and Indefinite Weight
In this article, we establish the existence and non-existence of solutions for quasilinear equations with nonlinear boundary conditions and indefinite weight. Our proofs are based on variational methods and their geometrical features. In addition, we prove that all the weak solutions are in C1,β(Ω) for some β ∈ (0, 1).
متن کاملExistence of at least three weak solutions for a quasilinear elliptic system
In this paper, applying two theorems of Ricceri and Bonanno, we will establish the existence of three weak solutions for a quasilinear elliptic system. Indeed, we will assign a differentiable nonlinear operator to a differential equation system such that the critical points of this operator are weak solutions of the system. In this paper, applying two theorems of R...
متن کاملQuasilinear Schrödinger equations involving critical exponents in $mathbb{textbf{R}}^2$
We study the existence of soliton solutions for a class of quasilinear elliptic equation in $mathbb{textbf{R}}^2$ with critical exponential growth. This model has been proposed in the self-channeling of a high-power ultra short laser in matter.

متن کاملAsymptotic behaviour of positive large solutions of quasilinear logistic problems
We are interested in the asymptotic analysis of singular solutions with blowup boundary for a class of quasilinear logistic equations with indefinite potential. Under natural assumptions, we study the competition between the growth of the variable weight and the behaviour of the nonlinear term, in order to establish the blow-up rate of the positive solution. The proofs combine the Karamata regu...
