Subject: 2 ?? rational homotopy theory From: jim stasheff Date: Fri, 09 Mar 2007 11:00:08 -0500 A_\infty or L_\infty algebras or morphisms can be described the old fashioned way in terms of component maps V^\otimes n \to V or via a coderivation D of square 0 on the bar construction or the analog for Lie homotopies of such morphisms are given as coderivation homotopies on the bar construction or the analog for Lie or via the Quillen version using V[t,dt] Is it written anywhere how these homotopies look in terms of component maps?? Has anyone looked at non-commutative rational homotopy theory? aka `quantum' rational homotopy theory? jim stasheff
