HYD2 - Dispersive hydrodynamics: mathematics, simulation and experiments, with applications in nonlinear waves

Solution structure preserving discretizations of integrable systems, i.e., integrable discretizations, have been actively studied in recent years.  We have obtained self-adaptive moving mesh schemes of several soliton equations involving hodograph transformations such that the Camassa-Holm equation  and the short pulse equation in which mesh intervals are automatically adjusted. I will talk about the construction of self-adaptive moving lattice schemes for the short pulse type equations under general boundary conditions and its application to numerical computations, as well as integrable discretizations of the SIR model.
