Реферат:	rus: Разработан и апробирован двухуровневый итерационный алгоритм поиска стационарных решений системы уравнений, описывающих динамику распространения электромагнитного поля в многоядерных волокнах центрально-симметричной структуры. На примере локализованного по пространству и времени солитонного решения выполнены тестовые расчеты и продемонстрирована сходимость алгоритма. eng: Multicore fiber is one of the main research trends in the field of nonlinear optics and photonics. Its broad application lies from optical switching devices to space division multiplexing as means of the high capacity fiber links that ensure the great potential and interest in such nonlinear fiber arrays. One of the challenges in the area is numerical construction of the stationary pulse solution in the irregular fiber structures. We consider multicore fiber consisting of radial equally distributed cores with the additional core in the center, which enters the irregularity. For such a system all the well-known numerical iterative methods tend to provide the trivial solution. To the best of our knowledge, we present the original iteration algorithm to construct the stationary solution in the multicore fiber of the irregular structure which is localized in time and space domains. Moreover, we prove the stability of the numerical solution using Vakhitov - Kolokolov criteria. The developed algorithm can be used for construction of the stationary solutions in multicore fibers of irregular structures.
