DESCRIPTION:Stationary distributions of vorticity in a two-dimensional flu
 id are considered where the vorticity support consists of points (point vo
 rtices) and curves (vortex sheets.)  The flow in many cases is determined 
 by a simple rational function.  By comparing the vorticity distributions t
 o point vortex configurations associated with polynomials\, these distribu
 tions can be related other questions such as non-uniqueness of Heine-Stiel
 tjes polynomials and to the asymptotics of some non-classical special case
 s of orthogonal polynomials.
