On the inverse problem of Lagrangian supermechanics
(34K, LaTeX)
ABSTRACT. The inverse problem for Lagrangian supermechanics is investigated.
A set of necessary and sufficient conditions for a system of second
order differential equations in superspace to derive from (a
possibly non regular) superlagrangian function are
given. The harmonic superoscillator is revisited and a family of
even and odd alternative superlagrangians are constructed for it.
Finally, we comment on the existence of recursion operators.
