Partial Lie-point Symmetries of Diierential Equations
When we consider a diierential equation = 0 whose set of solutions is S, a Lie-point exact symmetry of this is a Lie-point invertible transformation T such that T (S) = S, i.e. such that any solution to = 0 is tranformed into a (generally, diierent) solution to the same equation; here we deene partial symmetries of = 0 as Lie-point invertible transformations T such that there is a nonempty subs...
متن کاملReduction of Differential Equations by Lie Algebra of Symmetries
The paper is devoted to an application of Lie group theory to differential equations. The basic infinitesimal method for calculating symmetry group is presented, and used to determine general symmetry group of some differential equations. We include a number of important applications including integration of ordinary differential equations and finding some solutions of partial differential equa...
متن کاملLie Symmetries of Partial Differential Equations and Cr Geometry
This memoir is divided in three parts 1. Part I endeavours a general, new theory (inspired by modern CR geometry) of Lie symmetries of completely integrable PDE systems, viewed from their associated submanifold of solutions. Part II builds general combinatorial formulas for the prolongations of vector fields to jet spaces. Part III characterizes explicitly flatness of some systems of second ord...
متن کاملLie Symmetries of Differential Equations Byco~uteralgebra
In this paper we restrict ourselves to Lie point symmetries an applications to the fourth order generalized Burgers equation GBE4. Using computer programs under the computer algebra package MATHEMATIC A we find a three dimensional solvable Lie algebra of point symmetries of the GBE4 equation. The similarity reductions due to these symmetries have also been obtained. The idea of applying Lie gro...
متن کاملC∞−Symmetries and Reduction of Equations Without Lie Point Symmetries
It is proved that several usual methods of reduction for ordinary differential equations, that do not come from the Lie theory, are derived from the existence of C∞ -symmetries. This kind of symmetries is also applied to obtain two successive reductions of an equation that lacks Lie point symmetries but is a reduced equation of another one with a three dimensional Lie algebra of point symmetrie...
