| dc.description.abstract | We study the nonlinear eigenvalue problem -u″(t) = λ(u(t)p + g(u(t))), u(t) > 0, t ∈ (-1, 1), u(±1) = 0, where g(u) = h(u) sin(ur), p, r are given constants satisfying p ≥ 0, 0 < r ≤ 1 and λ > 0 is a parameter. It is known that under suitable conditions on h, λ is parameterized by the maximum norm α = ∥uα∥∞ of the solution uλ associated with λ and λ = λ(α) is a continuous function for α > 0. When p = 1, h(u) ≡ 1 and r = 1/2, this equation has been introduced by Chen [4] as a model equation such that there exist infinitely many solutions near λ = π2/4. We prove that λ(α). It is found that the shapes of bifurcation curves depend on the condition p > 1 or p < 1. The main tools of the proof are time-map argument and stationary phase method. | |
