Families of solution curves for some non-autonomous problems

The paper studies families of positive solution curves for non-autonomous two-point problems $u"+λf(u)-μg(x)=0, \;\; -1<x<1, \;\; u(-1)=u(1)=0$ depending on two positive parameters $λ$ and $μ$. We regard $λ$ as a primary parameter, giving us the solution curves, while the secondary parameter $μ$ allows for evolution of these curves. We give conditions under which the solution curves do not intersect, and the maximum value of solutions provides a global parameter. Our primary application is to constant yield harvesting for diffusive logistic equation. We implement numerical computations of the solution curves, using continuation in a global parameter, a technique that we developed in [11].
