Schemata of the Poisson bracket and BV Laplacian. a A diagrammatic depiction of a term in the Poisson bracket \(\{J,J'\}\). The Poisson bracket is the graded sum over all ways of contracting out one edge from J with one edge from \(J'\) with \(K_t\). b A diagrammatic depiction of a term in the BV Laplacian. It is a graded sum over all ways of contracting out pairs of edges in J with \(K_t\)
