ABSTRACT |
We consider the surface Stokes equation on a smooth closed hypersurface in R3. For discretization of this problem a generalization of the surface finite element method (SFEM) of Dziuk-Elliott combined with a Hood-Taylor pair of finite element spaces has been used in the literature.
We call this method Hood-Taylor-SFEM. This method uses a penalty technique to weakly satisfy
the tangentiality constraint. In this paper we present a discretization error analysis of this method
resulting in optimal discretization error bounds in an energy norm. We also address linear algebra
aspects related to (pre)conditioning of the system matrix. |
