On a wave equation with a boundary condition associated with capillary waves
(Siam Publications, 1998-09)
This paper discusses an initial-boundary value problem for a wave equation with a nonstandard boundary condition associated with linear capillary waves on the surface of a compressible liquid. We prove the well-posedness ...
Least-squares finite element approximations to solutions of interface problems
(Siam Publications, 1998-02)
A least-squares finite element method for second-order elliptic boundary value problems having interfaces due to discontinuous media properties is proposed and analyzed. Both Dirichlet and Neumann boundary data are treated. ...
