WebFeb 18, 2024 · To obtain an equivalence between $C_* (D_2)$ algebras and $H_* (D_2)$ algebras, one needs to choose a zig-zag of quasi-isomorphisms between the two operads. These formality isomorphisms are difficult to construct, and there are many possible choices, because these operads admit a large automorphism group. WebFormal group schemes are simply the group objects in a category of formal schemes; however usually only the case of the formal spectra of complete k k-algebras is considered; this category is equivalent to the category of complete cocommutative k k-Hopf algebras.
