Abstract: | We study the nonlinear Sturm-Liouville problem where λ > 0 is an eigenvalue parameter and f(u) is a rapidly increasing function. For better understanding of the global behavior of the bifurcation branch in R+ × L
2(I), we establish precise asymptotic formulas up to the third term for the eigenvalue λ(α) associated with the eigenfunction
u
α with ‖u
α‖2 = α, as α → ∞. We show that there exists a new type of asymptotic formula for λ (α) as α → ∞. |
