Synchronization of spiral wave patterns in coupled 2D lattices of discrete maps — •Andrei Bukh¹, Eckehard Schöll², and Vadim Anishchenko¹ — ¹Saratov State University, Saratov, Russia — ²Technical University, Berlin, Germany

We study numerically the dynamics of two symmetrically and unidirectionally coupled lattices of nonlocally coupled two-dimensional Nekorkin maps. The phenomena of external and mutual synchronization of spiral wave patterns including chimera states are explored. The partial and complete synchronization is analyzed by calculating the number of synchronous elements in the coupled lattices depending on the coupling strength between them. Synchronous regimes are quanitified by using mutual correlation coefficients between the relevant elements in the lattices.
