## Explicit L∞L_\infty-operations on Hochschild cochains of A∞A_\infty-algebra

It is well-known that the Hochschild cochain complex CC∗(A) of an associative algebra A carries a lot of structure. In particular: a differential, a cup product, and a bracket, which make the Hochschild cohomology HH∗(A) into a Gerstenhaber algebra. For concretenes, I have in mind that we’re using the standard bar complex model for CC∗ … Read more
