Web∞-ring spectra rather than A ∞-ring spectra. There is an existing literature on this topic developed by Robinson and others, some based on Γ-homology. See [36], [37], and [4]. This can be used, to prove, among other things, that the spectra E nare E ∞, and we guess that the obstruction theory we uncover here reduces to that theory. Another WebGiven a commutative base ring kand a k-algebra A, the Hochschild homology groups HH n(A=k), arising as the homology groups of the explicit Hochschild complex HH(A=k), were introduced already in the 1950s and are closely related to algebraic di erential forms: to be precise, if Ais commutative then there exist maps n A=k!HH
