  The Equations of motion of vortex sources (examined earlier by Fridman and
Polubarinova) are studied, and the problems of their being Hamiltonian and
integrable are discussed. A system of two vortex sources and three
sources-sinks was examined. Their behavior was found to be regular. Qualitative
analysis of this system was made, and the class of Liouville integrable systems
is considered. Particular solutions analogous to the homothetic configurations
in celestial mechanics are given.
