Abstract
Within the framework of the analytical asymptotic procedure, in the quadratic approximation in the small dimensionless amplitude of the capillary oscillation of a charged electroconductive fluid layer on the surface of a rigid spherical core, the problem of calculation of the free surface shape at an arbitrary moment is solved for a multimodal initial deformation. The conditions under which the internal nonlinear resonant interaction between the liquid layer oscillation modes and the intermodal energy exchange are realized are analyzed for both the degenerate and the secondary combinational resonances.
