Abstract
The stationary radial distribution, , of a random walk with the diffusion coefficient , which winds at the tangential velocity around an impenetrable disk of radius for converges to the distribution involving the Airy function. Typical trajectories are localized in the circular strip , where is a constant which depends on the parameters and and is independent of .
