On differential equations characterized by their Lie point symmetries

Journal of Mathematical Analysis and Applications, 2007
The authors study differential equations which are uniquely determined by their Lie point symmetries; they call such equations Lie remarkable. Using the jet bundle formalism a geometric characterisation of these equations is given. As two larger examples, minimal submanifold equations and Monge-Ampère equations are considered in some detail.

Projective Collineations of Decomposable Spacetimes Generated by the Lie Point Symmetries of Geodesic Equations

Symmetry, 2021
We investigate the relation of the Lie point symmetries for the geodesic equations with the collineations of decomposable spacetimes. We review previous results in the literature on the Lie point symmetries of the geodesic equations and we follow a ...

Lie-Point Symmetries and Backward Stochastic Differential Equations [PDF]

Symmetry, 2019
In this paper, we introduce the Lie-point symmetry method into backward stochastic differential equation and forward–backward stochastic differential equations, and get the corresponding deterministic equations.

Lie point symmetries of a general class of PDEs: The heat equation

Journal of Geometry and Physics, 2012
We give two theorems which show that the Lie point and the Noether symmetries of a second-order ordinary differential equation of the form (D/(Ds))(((Dx^{i}(s))/(Ds)))=F(x^{i}(s),x^{j}(s)) are subalgebras of the special projective and the homothetic algebra of the space respectively.
