Quasilinear Elliptic

Abstract The aim of this work is to study a quasilinear elliptic equation with singular nonlinearity and data measure. Existence and non-existence results are obtained under necessary or sufficient conditions on the data, where the main ingredient is the isoperimetric inequality. Finally, uniqueness results for weak solutions are given.

Special Case

In this paper, we establish sharp [Formula: see text] estimates for weak solutions of singular and degenerate quasilinear elliptic equation [Formula: see text] which includes the standard [Formula: see text]-Laplacian equation with varying coefficients as a special case. The sharp exponent [Formula: see text] is asymptotically optimal and is determined by the Hölder regularity of the coefficients, the exponent [Formula: see text] and the [Formula: see text]-integrability of the source term [Formula: see text].

Quasilinear Elliptic

The aim of this paper is investigating the multiplicity of weak solutions of the quasilinear elliptic equation [Formula: see text] in [Formula: see text], where [Formula: see text], the nonlinearity [Formula: see text] behaves as [Formula: see text] at infinity and [Formula: see text] is a potential satisfying suitable assumptions so that an embedding theorem for weighted Sobolev spaces holds. Both the non-resonant and resonant cases are analyzed.

Quasilinear Elliptic

We prove the existence of a simple, isolated, positive principal eigenvalue for the quasilinear elliptic equation−Δpu=λg(x)|u|p−2u,x∈ℝN,lim|x|→+∞u(x)=0, whereΔpu=div(|∇u|p−2∇u)is thep-Laplacian operator and the weight functiong(x), being bounded, changes sign and is negative and away from zero at infinity.
