复Ginzburg-Landau方程在一般区域上的局部适定性

Local well-posedness of the complex Ginzburg-Landau Equation in general domains

Takanori Kuroda, Mitsuharu Ôtani

摘要:

研究了具有超线性增长项的复Ginzburg-Landau(CGL)方程.讨论了一般区域上方程初边值问题在能量空间H1中的局部适定性。H1在有界域中的局部适定性已经被作者(2019)研究过。我们对CGL方程的研究是基于次微分算子控制的非单调扰动的抛物型方程的理论。利用这种方法,结合Yosida逼近方法,讨论了小初值条件下局部解的存在唯一性以及整体解的存在性.

英文摘要:

In this paper, complex Ginzburg-Landau (CGL) equations with superlinear growth terms are studied. We discuss the local well-posedness in the energy space H1 for the initial-boundary value problem of the equations in general domains. The local well-posedness in H1 in bounded domains is already examined by authors (2019). Our approach to CGL equations is based on the theory of parabolic equations governed by subdifferential operators with non-monotone perturbations. By using this method together with the Yosida approximation procedure, we discuss the existence and the uniqueness of local solutions as well as the global existence of solutions with small initial data.
