Abstract
The question of vanishing of the BV operator on the cohomology of the moduli space of Riemann surfaces is investigated. The BV structure, which comprises a BV operator and an antibracket, is identified, vanishing theorems are proven, and a counterexample is provided.

Bibliographical note
Funding Information:With admiration and gratitude, we dedicate this paper to Kyoji Saito. The breadth of his interests touched upon the topics of this paper as well: his recent paper [26] uses the BV-algebra of multivector fields on a Calabi-Yau manifold, whereas his interest in the moduli spaces is long-standing, see [35, 36, 37, 38]. We are grateful to Weiyan Chen, Domenico D?Alessandro, S?ren Galatius, and Craig Westerland for useful discussions. SS also thanks the Max Planck Institute for Mathematics, Bonn, for its great research environment and support. AV was supported by the World Premier International Research Center Initiative (WPI), MEXT, Japan, and a Collaboration grant from the Simons Foundation (#585720).
