Add to ORKGAbstract. We study positive solutions of an elliptic problem with indefinite in sign nonlinear Neumann boundary condition that depends on a real parameter, λ. We find precise range, I, of those λ’s for which our problem possesses a positive solution, prove that λ ∗ = sup I is a bifurcation point, and exhibit explicit max-min procedure for computing λ∗. We also obtain some properties of the set of solutions
