Spectrally Accurate Energy-preserving Methods for the Numerical Solution of the "Good" Boussinesq Equation
Luigi Brugnano, Gianmarco Gurioli, Chengjian Zhang
In this paper we study the geometric solution of the so called "good" Boussinesq equation. This goal is achieved by using a convenient space semi-discretization, able to preserve t…
