Semilinear Elliptic Problems with Pairs of Decaying Positive Solutions
Semilinear Elliptic Problems with Pairs of Decaying Positive Solutions
Our main objective is to prove the existence of a pair of positive, exponentially decaying, classical solutions of the semilinear elliptic eigenvalue problem 1.1 in a smooth unbounded domain Ω ⊂ R N , N ≧ 2, where λ is a positive parameter and L is a uniformly elliptic operator …
