摘要：The talk presents a new proof of the $C^0$IPG method ($C^0$ interior

penalty Galerkin method) for the biharmonic eigenvalue problem. Instead of

using the proof following the structure of discontinuous Galerkin method, we

rewrite the problem as the eigenvalue problem of a holomorphic Fredholm

operator function of index zero. The convergence for $C^0$IPG is proved

using the abstract approximation theory for holomorphic operator functions.

We employ the spectral indicator method which is easy in coding to compute

the eigenvalues. Numerical examples are presented to validate the theory.
