Abbreviations
- Perturbation theory :
-
A theory aiming at studying solutions of a differential equation (or system thereof), possibly depending on external parameters, near a known solution and/or for values of external parameters near to those for which solutions are known.
- Dynamical system :
-
A system of first order differential equations \({\text{d} x^i / \text{d} t = f^i (x,t)}\), where \({x \in M}\), \({t \in {\mathbf R}}\). The space M is the phase space for the dynamical system, and \({\widetilde{M} = M \times {\mathbf R}}\) is the extended phase space. When f is smooth we say the dynamical system is smooth, and for f independent of t, we speak of an autonomous dynamical system.
- Symmetry :
-
An invertible transformation of \({\widetilde{M}}\) mapping solutions into solutions. If the dynamical system is smooth, smoothness will also be required on symmetry transformations; if it is autonomous, it will be natural to consider transformations of M rather than of \({\widetilde{M}}\).
- Symmetry reduction :
-
A method to reduce the equations under study to simpler ones (e. g. with less dependent variables, or of lower degree) by exploiting their symmetry properties.
- Normal form :
-
A convenient form to which the system of differential equations under study can be brought by means of a sequence of change of coordinates. The latter are in general well defined only in a subset of M, possibly near a known solution for the differential equations.
- Further normalization :
-
A procedure to further simplify the normal form for a dynamical system, in general making use of certain degeneracies in the equations to be solved in the course of the normalization procedure.
