MiS Preprint Repository
We have decided to discontinue the publication of preprints on our preprint server end of 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
Temporal asymptotics for the p'th power newtonian fluid in one space dimension
Marta Lewicka and Stephen J. WatsonAbstract
In this paper we consider a variety of initial-boundary value problems for the p'th power Newtonian fluid in one space dimension. We extend previously known results for the ideal gas case to a more general p'th power gas law, subject to the pinned endpoints and Dirichlet or Neumann temperature boundary conditions. The exponential convergence of the temperature, velocity and density is established for generic initial data. The estimates for different boundary conditions are presented in a unified manner.
