EVOLUTION AND DYNAMICAL STABILIZATION OF MESOSCOPIC DISSIPATIVE STRUCTURES (ROTATING AUTOWAVES) WITH MULTIPLE TOPOLOGICAL CHARGES IN THREE- LEVEL EXCITABLE SYSTEMS
摘要
The paper is devoted to computer modeling of evolution of mesoscopic dissipative structures (DS), which emerge in three-level excitable systems of the phaser type. Particular attention is given to the study of the rotating helical autowaves (RHA), including the stable RHA with multiple topological charges. The dimensional phenomena for these RSA have been revealed and investigated in details in the computer experiments. The hypersensitivity to the initial conditions is demonstrated for a multistable excitable system having spatial attractors in the form of RSA with various higher topological charges. The phenomenon of spatial coexistence of regular and irregular DS during slow transient processes in excitable medium has first been modeled (such a phenomenon observed before in real experiments on the ruby phaser).
