Analysis of a Local Discontinuous Galerkin Method for Linear Time-Dependent Fourth-Order Problems

We analyze a local discontinuous Galerkin method for fourth-order time-dependent problems. Optimal error estimates are obtained in one dimension and in multidimensions for Cartesian and triangular meshes. We extend the analysis to higher even-order equations and the linearized Cahn-Hilliard type equations. Numerical experiments are displayed to verify the theoretical results.
