Title: Strong solutions for the Navier-Stokes equations on bounded and unbounded domains with a moving boundary Author: Juergen Saal (Univ. of Konstanz, Germany) Abstract: It is proved under mild regularity assumptions on the data that the Navier-Stokes equations in bounded and unbounded noncylindrical regions admit a unique local-in-time strong solution. The result is based on maximal regularity estimates for the in spatial regions with a moving boundary obtained in [16] and the contraction mapping principle. Published February 28, 2007.
