A Dynamical Theory of the Electromagnetic Field — which was written in the year 1864, is the third of James Clerk Maxwell s papers concerned with electromagnetism. It is the paper in which the original set of four Maxwell s equations first appeared. The concept of displacement current that he… … Wikipedia
Conserved quantity — In mathematics, a conserved quantity of a dynamical system is a function H of the dependent variables that is a constant (in other words, conserved)[1] along each trajectory of the system. A conserved quantity can be a useful tool for qualitative … Wikipedia
Separatrix (dynamical systems) — In mathematics, a separatrix refers to the boundary separating two modes of behaviour in a differential equation. ExampleConsider the differential equation describing the motion of a simple pendulum::{d^2 hetaover dt^2}+{gover l} sin heta=0.… … Wikipedia
Second class constraints — In a constrained Hamiltonian system, a dynamical quantity is second class if its Poisson bracket with at least one constraint is nonvanishing. A constraint that has a nonzero Poisson bracket with at least one other constraint, then, is a second… … Wikipedia
