Liouville type theorem for higher order Hardy-Hénon system of inequalities

, 2014
In this paper, we prove some new Liouville type theorems for fourth order and more general higher order Hardy-Henon systems of inequalities. The test function method is applied to show the nonexistence of nontrivial nonnegative global solutions, which ...

On entire solutions for an indefinite quasilinear system of mixed power

, 2014
We prove non-existence and existence of entire positive solutions for a Schrodinger 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 ...

A Liouville comparison principle for solutions of quasilinear singular parabolic inequalities

Advances in Nonlinear Analysis, 2015
We obtain a Liouville comparison principle for entire weak solutions (u,v) of quasilinear singular parabolic second-order partial differential inequalities of the form ut-A(u)-|u|q-1u≥vt-A(v)-|v|q-1v${ u_t - A(u)-|u|^{q-1}u \ge v_t - A (v)-|v|^{q-1}v ...

A Liouville-Type Theorem for an Elliptic Equation with Superquadratic Growth in the Gradient

Advanced Nonlinear Studies, 2020
We consider the elliptic equation -Δ⁢u=uq⁢|∇⁡u|p{-\Delta u=u^{q}|\nabla u|^{p}} in ℝn{\mathbb{R}^{n}} for any p>2{p>2} and q>0{q>0}. We prove a Liouville-type theorem, which asserts that any positive bounded solution is constant.

Positive Solutions for Systems of Quasilinear Equations with Non-homogeneous Operators and Weights

Advanced Nonlinear Studies, 2020
In this paper we deal with positive radially symmetric solutions for a boundary value problem containing a strongly nonlinear operator. The proof of existence of positive solutions that we give uses the blow-up method as a main ingredient for the search ...
