我们考虑种群动力学中的非线性分支问题和非线性薛定谔方程:其中λ>0是参数。我们主要处理f(U)=λu±up(p>1)的情形,并在Lq-框架中建立了分支曲线在分岔点λ=π2附近的精确渐近展开公式。结合分叉曲线全局行为的结果,我们完全了解了分叉曲线的结构。我们还考虑了方程λu“(T)=−(u(T)+|u(T)|pλ1u(T))的节点解un,−当u(0)=u(π)=0时,建立了λ关于λ的解的梯度范数的渐近展开式为λ→n2。
We consider the nonlinear bifurcation problem arising in population dynamics and nonlinear Schrödinger equation: where λ>0 is a parameter. We mainly treat the case where f(u)=λu±up(p>1) and establish the precise asymptotic expansion formulas for the bifurcation curve near the bifurcation point λ=π2in Lq-framework. Together with the result of the global behavior of the bifurcation curve, we understand completely the structure of the bifurcation curve. We also consider the nodal solution un,λof the equation −u″(t)=λ(u(t)+|u(t)|p−1u(t)) with u(0)=u(π)=0 and establish an asymptotic expansion formula for λ with respect to the gradient norm of the solution associated with λ as λ→n2.
