Action-angle coordinates for the pendulum problem
Alain J. Brizard
The action-angle coordinates for the planar pendulum problem are expressed in terms of the Jacobi elliptic functions and integrals. In particular, we show that the Jacobi zeta func…

Exact momentum conservation laws for the gyrokinetic Vlasov-Poisson equations
Alain J. Brizard, Natalia Tronko
The exact momentum conservation laws for the nonlinear gyrokinetic Vlasov-Poisson equations are derived by applying the Noether method on the gyrokinetic variational principle [A.…
