We show that the normalized cochain complex of a nonsymmetric cyclic operad with multiplication is a Quesney homotopy BV algebra;as a consequence,the cohomology groups form a Batalin-Vilkovisky algebra,which is a resu...
We present a deformation theory associated to the higher Hochschild coho-mology H*_(S)^(2)(A,A).We also study a G-algebra structure associated to this deformation theory.
