Abstract in different language: This paper analyzes the structure of the set of positive solutions of a class of one-dimensional superlinear indefinite bvp’s. It is a paradigm of how mathematical analysis aids the numerical study of a problem,whereas simultaneously its numerical study confirms and illuminates the analysis. On the analytical side, we establish the fast decay of the positive solutions as λ ↓ −∞ in the region where a(x) < 0 (see (1.1)), as well as the decay of the solutions of the parabolic counterpart of the model (see (1.2)) as λ ↓ −∞on any subinterval of [0, 1] where u0 = 0, provided u0 is a subsolution of (1.1). This result provides uswith a proof of a conjecture of [26] under an additional condition of a dynamical nature. On the numerical side, this paper ascertains the global structure of the set of positive solutions on some paradigmatic prototypes whose intricate behavior is far from predictable from existing analytical results.
