Abstract
The work is aimed investigating the evolution of chimera states in ensembles of nonlocally coupled logistic, cubic and Ricker maps when the coupling coefficients are modulated with colored Gaussian noise. The main objective of the study is to analyze the influence of random noise impacts on the spatiotemporal dynamics of ensembles with different partial elements, as well as to identify the possibilities of controlling the initial dynamic regimes of systems (chimera states). We found out that the type of map used affects the number of regimes appears under noise influence, from the partial or complete synchronization (including chimeras and solitary states) to the spatiotemporal chaos and the solutions going to infinity.
