We show that any homotopy Gerstenhaber algebra is naturally a strongly homotopy commutative (shc) algebra in the sense of Stasheff–Halperin with a homotopy associative structure map. In the presence of certain additional operations corresponding to a \(\mathbin {\cup _1}\)-product on the bar construction, the structure map becomes homotopy commutative, so that one obtains an shc algebra in the sense of Munkholm.

同伦Gerstenhaber代数是强同伦可交换的
我们证明,从Stasheff–Halperin的意义上讲,任何同伦Gerstenhaber代数自然都是强同伦可交换(shc)代数,具有同伦关联结构图。在杆构造上存在与\(\ mathbin {\ cup _1} \)乘积相对应的某些附加运算时,结构图变为同伦可交换的,因此可以得到Munkholm的shc代数。
