  We introduce the Virasoro symmetry in the BV formalism and give an explicit
construction of the anti-bracket, which is Virasoro invariant. It is shown that
the master equation with this anti-bracket has an infinite number of solutions.
The base space of the BV formalism is a fermionic version of the Virasoro
manifold $Diff(S^1)/S^1$. We discuss also the Ricci tensor of this fermionic
manifold.
