We consider the problem of asymptotic stability and linear inviscid dampingfor perturbations of a point vortex and similar degenerate circular flows.Here, key challenges include the lack of strict monotonicity and the necessityof working in weighted Sobolev spaces whose weights degenerate as the radiustends to zero or infinity. Prototypical examples are given by circular flowswith power law singularities or zeros as $r\downarrow 0$ or $r \uparrow\infty$.

On degenerate circular and shear flows: the point vortex and power law circular flows
