Optimally convergent hybridizable discontinuous Galerkin method for fifth-order Korteweg-de Vries type equations

Bo Dong, Jiahua Jiang, Yanlai Chen

We develop and analyze the first hybridizable discontinuous Galerkin (HDG) method for solving fifth-order Korteweg-de Vries (KdV) type equations. We show that the semi-discrete sch…
