Abstract
We perform an Hamiltonian reduction on a classical (, ) algebra, and prove that we get another (, ') algebra, with ⊂'. In the case =S(n), the existence of a suitable gauge, called Generalized Horizontal Gauge, allows to relate in this way two -algebras as soon as their corresponding -algebras are related by inclusion.
