A Note on the Positive Solutions of an Inhomogeneous Elliptic Equation on Rn
Journal of Differential Equations
(2009)
Abstract
This paper is contributed to the elliptic equation (0.1) Δu+K(|x|)up+μf(|x|)=0,
where p>1, x∈Rn, n⩾3, and μ⩾0 is a constant. We study the structure of positive radial solutions of (0.1) and obtain the uniqueness of solution decaying faster than r−m at ∞ if μ is small enough under some assumptions on K and f, where m is the slow decay rate.
