Note on the cohomology of color Hopf and Lie algebrasLet A be a ( G , 蠂 )-Hopf algebra with bijective antipode and let M be a G-graded A-bimodule. We prove that there exists an isomorphism HH gr ( A , M ) Ext A -gr ( K , ( M ) ad ) , where K is viewed as the ...

The (right-) Sn-representation on En(j) is well-studied, by Hanlon [9] and others: The En(j) also have an interpretation in terms of cohomology of configuration spaces. Throughout this paper, for a topological space X, all cohomology ⁎H⁎X will mean singular cohomology ⁎H⁎(X...
) become much simpler. In particular, one can compute the cohomology of (e.g., from the cohomology of ), and one finds that it is cyclic over the Steenrod algebra. One can then try to “descend” to the cohomology of . This “descent” procedure is made much simpler by a battery of...
