考虑方程−u″(t)+ sinu(t)=λu(t),u(t)> 0,t∈I=:(0,1),u(0)=u(1)= 0的非线性特征值问题,其中λ> 0为参数.已知对于给定的ε> 0,存在唯一解对。我们建立了分支曲线λ(λ)在λ →∞和λ → 0时的精确渐近公式,以了解正弦曲线的振动性对λ(λ)的行为的影响。我们还建立了分支曲线λ(α)的精确渐近公式,以说明λ(α)与λ(λ(α)的区别。
We consider the nonlinear eigenvalue problems for the equation −u″(t) + sinu(t) =λu(t),u(t) > 0,t∈I= :(0, 1),u(0) =u(1) = 0, whereλ> 0 is a parameter. It is known that for a givenξ> 0, there exists a unique solution pairwith. We establish the precise asymptotic formulas for bifurcation curveλ(ξ) asξ→∞andξ→0to see how the oscillation property of sinuhas effect on the behavior ofλ(ξ). We also establish the precise asymptotic formula for bifurcation curveλ(α)to show the difference betweenλ(ξ) andλ(α).
