Multiple Positive Solutions for a Class of Concave-Convex Semilinear Elliptic Equations in Unbounded Domains with Sign-Changing Weights
Boundary Value Problems volume 2010, Article number: 856932 (2010)
We study the existence and multiplicity of positive solutions for the following Dirichlet equations: in , on , where , ( if ; if ), is a smooth unbounded domain in , , and satisfy suitable conditions, and maybe change sign in .
