Abstract

This project is concerned with the existence and stability of travelling waves of some deterministic (zero noise) nonlinear Partial Differential Equations (PDEs) of second order classified by A. Hone, V. Novikov and J. Wang, in 2018 (Reference [36] in the Research Project). This family of nonlinear partial differential equations of second order contains the important integrable equations of Ostrovsky-Hunter and Hunter-Saxton. We also intend to prove the existence of travelling wave solutions for some stochastic (additive and multiplicative) perturbations of this same family of nonlinear PDEs of second order and study the properties of these solutions.
