Existence of Positive Solutions to a Superlinear Elliptic Problem
MetadataShow full metadata
We study the existence of positive solutions to the semilinear elliptic problem
-∊2 ∆u + V(z)u = ƒ(u)
in ℝN (N ≥ 2), where the function ƒ has superlinear growth at infinity without any restriction from aboveon its growth.
