Abstract

The main purpose of the present paper is to study the asymptotic behavior near the origin of radial solutions of the equation 𝚫p u(x) + uq(x) + f(x) = 0 in ℝN\{0}, where p > 2, q > 1, N ≥ 1 and f is a continuous radial function on ℝN\{0}. The study depends strongly of the sign of the function f and the asymptotic behavior near the origin of the function |x|λf(|x|) with suitable conditions on λ > 0.
