A weakly over-penalized symmetric interior penalty method

We introduce a new symmetric interior penalty method for symmetric positive definite second order elliptic boundary value problems, where the jumps across element boundaries are weakly over-penalized. Error estimates are derived in the energy norm and the [L.sub.2] norm for both conforming and nonco...

Summary:We introduce a new symmetric interior penalty method for symmetric positive definite second order elliptic boundary value problems, where the jumps across element boundaries are weakly over-penalized. Error estimates are derived in the energy norm and the [L.sub.2] norm for both conforming and nonconforming meshes. Numerical results illustrating the performance of the method are also presented.
