论文摘要
我们证明了圆形和球形几何形状中复杂的金茨堡 - 兰道方程的$ M $臂螺旋波解决方案。我们建立了一种新的全球分叉方法,并概括了刚性旋转的螺旋波的存在结果。此外,我们证明存在两种新模式:圆形和球形几何形状中的冷冻螺旋,以及球形几何形状中的2尖螺旋。
We prove the existence of $m$-armed spiral wave solutions for the complex Ginzburg-Landau equation in the circular and spherical geometries. We establish a new global bifurcation approach and generalize the results of existence for rigidly-rotating spiral waves. Moreover, we prove the existence of two new patterns: frozen spirals in the circular and spherical geometries, and 2-tip spirals in the spherical geometry.
