Asymptotics of steady vortex pair in the lake equation. (Asymptotic of steady vortex pair in the lake equation.) (English) Zbl 1445.76030
The author considers a steady 2D Euler system for a multiconnected domain. The continuity and transport equations of incompressible fluid are added to prescribed circulations along each connected component. The asymptotic behaviour of shrinking vortex pairs is studied. The results show that each vortex is concentrated in some ball.
