LIE REMARKABLE PDEs

Asymptotic Methods in Nonlinear Wave Phenomena, 2007
Within the context of the inverse Lie problem the question whether there exist PDEs that are characterized by their Lie point symmetries may be addressed. In a recent paper the authors called these equations Lie remarkable. In this paper we exhibit various examples of Lie remarkable equations, including some multidimensional Monge-Ampere type equations.

Extremum seeking boundary control for PDE–PDE cascades

Systems & Control Letters, 2021
The manuscript addresses the problem of extremum seeking for wave equations evolving in the one-dimensional spatial interval~\((0,1)\subset\mathbb R\). \par The input control acts on the right spatial boundary point~\(x=1\); see Eqs.~(4)--(7). The authors also consider the case where such input is subject to the solution of a heat equation; see Eqs ...
