Strong comparison principle for solutions of quasilinear equations

A Liouville comparison principle for solutions of quasilinear differential inequalities

This work is devoted to the study of a Liouville comparison principle for entire weak solutions of quasilinear differential inequalities of the form A(u) + |u|q−1u ≤ A(v) + |v|q−1v on Rn, where n ≥ 1, q > 0, and the operator A(w) belongs to a class of the so-called α-monotone operators. Typical examples of such operators are the p-Laplacian and its well-known modifications for 1 < p ≤ 2. The re...

A Strong Comparison Principle for Positive Solutions of Degenerate Elliptic Equations

A strong comparison principle (SCP, for brevity) is obtained for nonnegative weak solutions u ∈ W 1,p 0 (Ω) of the following class of quasilinear elliptic boundary value problems, (P ) −div(a(x,∇u))− b(x, u) = f(x) in Ω; u = 0 on ∂Ω. Here, p ∈ (1,∞) is a given number, Ω is a bounded domain in IR with a connected C-boundary, a(x,∇u) and b(x, u) are slightly more general than the functions a0(x)|...

Soliton Solutions for Quasilinear Schrödinger Equations, I
