Instability induced by symmetry reduction

Physical Review Letters, 1992
Summary: We demonstrate that instabilities in a Hamiltonian system can occur via deformations that reduce the symmetry of the system. The movement of eigenvalues at an equilibrium point of a family of Hamiltonian systems is constrained by the symmetry type of the system.

VARIATIONAL CALCULUS, SYMMETRIES AND REDUCTION

International Journal of Geometric Methods in Modern Physics, 2006
Variational Principles and Symmetries are both fundamental ingredients of the most relevant (either classical or modern) physical theories, and of many interesting models in Pure and Applied Mathematics. While the variational principle determines the law (differential and sometimes algebraic equations) of the dynamics, the symmetries give way to ...

Localization of Nonlocal Symmetries and Symmetry Reductions of Burgers Equation

Communications in Theoretical Physics, 2017
Summary: The nonlocal symmetries of the Burgers equation are explicitly given by the truncated Painlevé method. The auto-Bäcklund transformation and group invariant solutions are obtained via the localization procedure for the nonlocal residual symmetries.

Reduction of Network States Under Symmetries

Bell System Technical Journal, 1978
It is a folk-theorem of traffic theory that if all sources have the same stochastic behavior, then symmetries of a telephone connecting network can be used to lump together equivalent states and to reduce the number of equations to be solved for the state probabilities.

REDUCTION OF DIFFERENTIAL EQUATIONS WITH SYMMETRIES

Mathematics of the USSR-Izvestiya, 1981
A method for constructing group-invariant solutions of differential equations is described. At the foundation of the method lies a reduction of the dimension of the base of a bundle of -jets of functions by means of a passage to the manifolds of orbits of the contact action of the Lie group of partial symmetries of the differential equation.

Lie symmetries and reductions

2009
Abstract Phrases like ‘the unifying role of symmetry in . . . ‘ feature prominently in the popular science literature. Depending on the subject, the symmetry may be ‘cosmic’, ‘Platonic’, ‘perfect’, ‘broken’, or even ‘super’.

Group actions, symmetries and reduction

2009
Abstract An action of a group on a set is a map that associates to each element of the group an invertible transformation of the given set, in such a way that the group operation corresponds to composition of transformations. Thus, the group may be thought of as a group of transformations.
