建立了周期平稳解的三次五次复Ginzburg-Landau方程线性化的单算子的存在性和正则性。我们用相关的渐近线性微分算子的本质谱导出了单算子的本质谱的表达式。在假定金兹堡-朗道方程包含谱滤波(扩散)项的情况下,利用解析半群理论得到了这一结果。我们讨论了周期性静止脉冲在超快光纤激光器稳定性中的应用。
We establish the existence and regularity properties of a monodromy operator for the linearization of the cubic–quintic complex Ginzburg–Landau equation about a periodically stationary (breather) solution. We derive a formula for the essential spectrum of the monodromy operator in terms of that of the associated asymptotic linear differential operator. This result is obtained using the theory of analytic semigroups under the assumption that the Ginzburg–Landau equation includes a spectral filtering (diffusion) term. We discuss applications to the stability of periodically stationary pulses in ultrafast fiber lasers.
