摘  要：A classical model for sources and sinks in a 2D perfect incompressible fluid dates back to Yudovich in 1966. In the most simple geometrical setting, the source releases a prescribed vorticity from a smooth hole into the surrounding fluid, which is driven by the incompressible Euler equations, and the fluid escapes the domain by a second hole.  The goal of the talk is to exhibit a limit system when the domains occupied by the source and by the sink shrink to two different points. This is a joint work with Marco Bravin.
