This bracket is compatible with the graded commutative product in cohomology, and hence gives rise to a new class of examples of what mathematicians call a {\\em Gerstenhaber algebra}. The latter structure was first discussed in the context of Hochschild cohomology theory \\cite{Gers1}. Off-shell in the (chiral) BRST complex, all the identities of a Gerstenhaber algebra hold up to homotopy. Applying","authors_text":"Bong H. Lian, Gregg J.
