AbstractA differential action principle written as follows, δq = − ∂δW∂p; δp = ∂δW∂q, is obtained by means of variations of the action integral. It yields Hamilton's equations of motion, provides a general method to treat perturbations in Classical Mechanics, and corresponds to Schwinger's principle of Quantum Mechanics
