Symmetry, Singularities and Integrability in Complex Dynamics III: Approximate Symmetries and Invariants
The different natures of approximate symmetries and their corresponding first integrals/invariants are delineated in the contexts of both Lie symmetries of ordinary differential equations and Noether symmetries of the Action Integral. Particular note is taken of the effect of taking higher orders of the perturbation parameter. Approximate symmetries of approximate first integrals/invariants and...
متن کاملSymmetry, Singularities and Integrability in Complex Dynamics Iv: Painlevé Integrability of Isotropic Cosmologies
In the modelling of various phenomena in relativistic cosmology the final result of the modelling process is a system of ordinary differential equations, whose solution is by no means obvious. Generally these systems are of the first order and autonomous, so that, if the system is two-dimensional, one is assured of the existence of solutions under mild conditions on the terms in the equations. ...
متن کاملSymmetry, singularities and integrability in complex dynamics II: Rescaling and time-translation in two-dimensional systems
Abstract: The explicit integrability of second order ordinary differential equations invariant under time-translation and rescaling is investigated. Quadratic systems generated from the linearisable version of this class of equations are analysed to determine the relationship between the Painlevé and singularity properties of the different systems. The transformation contains a parameter and fo...
متن کاملSymmetry, Singularities and Integrability in Complex Dynamics I: The Reduction Problem
Quadratic systems generated using Yang-Baxter equations are integrable in a sense, but we display a deterioration in the possession of the Painlevé property as the number of equations in each ‘integrable system’ increases. Certain intermediate systems are constructed and also tested for the Painlevé property. The Lie symmetries are also computed for completeness.
متن کاملSymmetry, singularities and intregrability in complex dynamics VII: Integrability Properties of FRW-Scalar Cosmologies
This paper considers some physically interesting cosmological dynamical systems in the FRW-scalarfield category which are examined for integrability according to the criterion of Painlevé. In the literature these systems have been examined from the point of view of dynamical systems and the results from the two disparate methods of analysis are compared. This allows some more general comments t...
