Geometry on formal duals of algebras
A Batalin-Vilkovisky algebra or BV-algebra for short is
a Gerstenhaber algebra
equipped with a unary linear operator of degree +1
is a derivation for ;
is the failure of being a derivation for :
A -BV algebra is a similar structure with a BV-operator being of degree if is odd, and of degree if it is even.
See (CohenVoronov, def. 5.3.1) for details.
This is due to (Getzler)
This appears as (CohenVoronov, theorem 5.3.3). The full homology of the framed little n-disk operad is described by (SalvatoreWahl, theorem 5.4).
Multivector fields may be identified with Hochschild cohomology in good cases (the Hochschild-Kostant-Rosenberg theorem). So the next example is a generalization of the previous one.
The identification o BV-algebras as algebras over the homology of the framed little disk operad is due to
- Ezra Getzler, Batalin-Vilkovisky algebras and two-dimensional topological field theories , Comm. Math. Phys. 159 (1994), no. 2, 265–285. (arXiv)
The generalization to higher dimensional framed little disks is discussed in

There are examples coming from Lagrangian intersection theory

The BV-algebra structure on multivector fields on an oriented smooth manifold is discussed for instance in section 2 of
and on p. 6 of

The BV-algebra structure on Hochschild cohomology is discussed for instance in
