摘要
In this paper, we study the existence of positive solutions and sign-changing solutions for the following boundary value problem in the half-space Delta u = 0, in R-+(N+1), partial derivative u/partial derivative n + lambda g(x)u = f(u), on partial derivative R-+(N+1), where lambda is a positive parameter and the nonlinear term f is superlinear at zero and asymptotically linear at infinity.
