We present a proof that a system consisting of any finite number of particles that move under the action of a scalar potential at constant kinetic energy exhibits conjugate pairing of Lyapunov exponents; that is, the Lyapunov exponents come in pairs, which sum to the same constant. This result generalizes previous results, because it is independent of the size of the system. @S1063-651X~96!51206-7#

Dynamical Systems and Statistical Mechanics: Lyapunov Exponents and Transport Coefficients
A brief survey is given of the derivation of an expression for the shear viscosity coefficient of a fluid in a nonequilibrium stationary state in terms of its maximal Lyapunov exponents. This is done
On the Validity of the Conjugate Pairing Rule for Lyapunov Exponents
For Hamiltonian systems subject to an external potential which in the presence of a thermostat will reach a nonequilibrium stationary state Dettmann and Morriss proved a strong conjugate pairing rule
The conjugate-pairing rule for non-Hamiltonian systems.
TLDR
Computer simulations provide convincing evidence that the standard molecular dynamics algorithm for calculating shear viscosity violates the Conjugate Pairing Rule, and it appears that the sum of the maximal exponents is equal to the entropy production per degree of freedom.
Fluctuation relation and pairing rule for Lyapunov exponents of inertial particles in turbulence
We study the motion of small particles in a random turbulent flow assuming a linear law of friction. We derive a symmetry relation obeyed by the large deviations of the finite-time Lyapunov exponents
Finite-size scaling of Lyapunov spectra for quasi-one-dimensional hard discs
We present numerical evidence for the existence of the thermodynamic limit in the Lyapunov spectrum of a quasi-one-dimensional system of hard discs. The spectrum for a system of 200 discs represents
