    "abstract": "In our paper [Markl, Shnider: Drinfel\u0027d Algebra Deformations and the\nAssociahedra, IMRN 1994, no. 4, 169-176] we announced a construction of a\ncohomology controlling deformations of quasi-coassociative (or Drinfel\u0027d)\nbialgebras. The full version of the paper will appear as [Markl, Shnider:\nDrinfel\u0027d Algebra Deformations, Homotopy Comodules and the Associahedra] in\nTrans. Amer. Math. Soc. The construction in the paper was based on very\nexplicit arguments using deep combinatorial properties of the associahedra. The\npresent paper gives an alternative, general nonsense approach to the\nconstruction. So, we just prove the existence of such a cohomology without\nexplicitly constructing it. This should be compared with the two approaches to\nthe cohomology of associative algebras: we either describe explicitly the\nHochschild complex and say \"Behold! this is the cohomology\" or we prove the\nexistence of a projective resolution and define the cohomology as the derived\nfunctor.",
