摘要：
We study the time evolution of a viscous incompressible fluid in R-2 when the initial vorticity is sharply concentrated in N regions of diameter epsilon. We prove that in the zero viscosity limit it converges as epsilon vanishes to the inviscid fluid and in particular to the point vortex system.
