Summary
Suppose Ω is a bounded region inR n. In this paper we investigate the equationLu=λF(x, u),u|∂Ω=0 whereL is an elliptic partial differential operator and V 3F(x, t) is a positive function on ΩxR 1 which may have jump discontinuities with respect tot. We show that if certain conditions are satisfied there exists an unbounded continuum Λ of solutions (γ, u), withu(x)≥0, in the spaceR 1×S. HereS is a Banach space of real valued functions such as\(C\left( {\bar \Omega } \right) \)
