Abstract

A general problem of motion of incompressible liquid with vortex zones with different constant vorticity is formulated. It is considered the M.A.Goldshtic variational method of the research of dual problems for flows with vortex and potential areas that describe the model of separated flows and the model of ideal liquid motion in a field of Coriolis forces. It is proved the existence of the second nontrivial solution to the M.A.Goldshtick problem.
