Poincare normal forms and Lie point symmetries

Journal of Physics A: Mathematical and General, 1994
Summary: We study Poincaré normal forms of vector fields in the presence of symmetry under general -- i.e. not necessarily linear -- diffeomorphisms. We show that it is possible to reduce both the vector field and the symmetry diffeomorphism to normal form by means of an algorithmic procedure similar to the usual one for Poincaré normal forms without ...

On Lie point symmetries in mechanics

Il Nuovo Cimento B Series 11, 1992
We present some remarks on the existence and the properties of Lie point symmetries of finite dimensional dynamical systems expressed either in Newton-Lagrange or in Hamilton form. We show that the only Lie symmetries admitted by Newton-Lagrange-type problems are essentially linear symmetries, and construct the most general problem admitting such a ...

Lie Point Symmetries of Differential-Difference Equations

Communications in Theoretical Physics, 2004
Summary: In this paper, the classical Lie group approach is extended to find some Lie point symmetries of differential-difference equations. It reveals that the obtained Lie point symmetries can constitute a Kac--Moody--Virasoro algebra.

Riemann's equation and Lie point symmetries

Physica Scripta, 2006
Riemann derived two equations for unsteady isentropic one-dimensional fluid flow which by means of a transformation can be conflated into a single equation. We perform a symmetry analysis of this equation and find that the number of Lie point symmetries is not what one would expect for an hyperbolic equation.
