Weak selection and stability of localized distributions in Ostwald ripening
We support and generalize a weak selection rule predicted recently for the
self-similar asymptotics of the distribution function (DF) in the
zero-volume-fraction limit of Ostwald ripening (OR). An asymptotic perturbation
theory is developed that, when combined with an exact invariance property of
the system, yields the selection rule, predicts a power-law convergence towards
the selected self-similar DF and agrees well with our numerical simulations for
the interface- and diffusion-controlled OR.Comment: 4 pages, 2 figures, submitted to PR
