“…One approach is to use the Hochschild cohomology of closed Frobenius algebras [CJ02,Mer04,Tra08,TZ06,Kau07,Kau08,Men09,WW]. In particular Félix-Thomas [FT08] proved that over rationals and for any closed simply connected manifold M the Chas-Sullivan BV-algebra H * (LM ) is isomorphic to HH * (A) := HH * (A, A ∨ ) where A is a finite dimensional model (i.e.…”

Abstract. We prove that the shifted Hochschild chain complex C * (A, A) [m] of a symmetric open Frobenius algebra A of degree m has a natural homotopy coBV-algebra structure. As a consequence HH * (A, A) [m] and HH * (A, A ∨ )[−m] are respectively coBV and BV algebras. The underlying coalgebra and algebra structure may not be resp. counital and unital. We also introduce a natural homotopy BV-algebra structure on C * ( is an open Frobenius algebras. If A is commutative, we also introduce a natural BV structure on the shifted relative Hochschild homology HH * (A)[m− 1]. We conjecture that the product of this BV structure is identical to the GoreskyHingston[GH09a] product on the cohomology of free loop spaces when A is a commutative cochain algebra model for M .
