Nilpotent Classical Mechanics
Abstract
Description
The formalism of nilpotent mechanics is introduced in the Lagrangian and Hamiltonian form. Systems are described using nilpotent, commuting coordinates $η$. Necessary geometrical notions and elements of generalized differential $η$-calculus are introduced. The so called $s-$geometry, in a special case when it is orthogonally related to a traceless symmetric form, shows some resemblances to the symplectic geometry. As an example of an $η$-system the nilpotent oscillator is introduced and its supersymmetrization considered. It is shown that the $R$-symmetry known for the Graded Superfield Oscillator (GSO) is present also here for the supersymmetric $η$-system. The generalized Poisson bracket for $(η,p)$-variables satisfies modified Leibniz rule and has nontrivial Jacobiator.
