Constrained Poisson algebras and strong homotopy representations
Constrained Poisson algebras and strong homotopy representations
A Poisson algebra is a commutative associative algebra A with an (anticommutative) bracket { , } which is a derivation with respect to the commutative product: {f,gh} = {f,g}h + /{g^h}.Constraints constitute a distinguished set of elements (j) a of A. They are said to be first class constraints if …
