Menichi, Luc Batalin-Vilkovisky algebra structures on Hochschild cohomology. (English) Zbl 1180.16007 Bull. Soc. Math. Fr. 137, No. 2, 277-295 (2009). Let \(\mathbb{F}\) be an arbitrary field, \(M\) be a compact oriented \(d\)-dimensional smooth manifold and \(LM\) be the free loop space on \(M\). The author proves that, if \(M\) is simply connected, then the Gerstenhaber algebra structure on the Hochschild cohomology of the algebra of singular cochains of \(M\) extends to a Batalin-Vilkovisky algebra structure isomorphic to that on \(H_{*+d}(LM)\), the shifted free loop space homology on \(M\).
