Abstract:
In this paper we construct a small $E_\infty$ chain operad $\mathcal {S}$ which acts naturally on the normalized cochains $S^*X$ of a topological space. We also construct, for each $n$, a suboperad $\mathcal {S}_n$ which is quasi-isomorphic to the normalized singular chains of the little $n$-cubes operad. The case $n=2$ leads to a substantial simplification of our earlier proof of Deligne’s Hochschild cohomology conjecture.References
