							| Abstract:  
							We consider a bidimensional incompressible viscous flow in the exterior of an 
obstacle that shrinks to a point. Under the hypothesis that 1) the initial 
vorticity and velocity's circulation on the boundary of the obstacle are 
independent of the obstacle and 2) the velocity's circulation is small 
independently of the size of the obstacle, we determine the limit velocity. This 
result extends a previous paper by the same authors which deals with the same 
problem in the inviscid case. This is work in collaboration with M. Lopes and H. 
Nussenzveig Lopes.
