Abstract
Two-dimensional autonomous systems with homogeneous cubic nonlinearities are considered. Simultaneous bifurcation from centers in $(x_i, y_i)\not=(0, 0),\; i=1, 2$ is investigated. Classes of systems with seven limit cycles with distributions $(1) \supset ((3) + (3)),\; (1) + (3) + (3) $ are described.Byelorussian State University of Informatics and Radioelectronics
