Regularity and singularity of weak solutions to Ostwald-de Waele flows

Hyeong-Ohk Bae, Hi Jun Choe, and Do Wan Kim

Abstract

We find a regularity criterion for the Ostwald-de Waele models like Serrin's condition to the Navier-Stokes equations. Moreover, we show short time existence and estimate the HausdOlif dimension of the set of singular times for the weak solutions.

Keywords: Ostwald-de Waele flow, regularity, Hausdorff dimension singularity, Serrin's condition
