Deligne猜想的一个解

A solution of Deligne's conjecture

James E. McClure, Jeffrey H. Smith

摘要:

Deligne在1993年问是否Hochschild上链复形的结合环有一个自然的行动的奇异链的小2立方运算。本文对此问题给予肯定的回答。我们还证明了结合环谱的拓扑Hochschild上同调谱具有等价于小2-立方的运算作用。

英文摘要:

Deligne asked in 1993 whether the Hochschild cochain complex of an associative ring has a natural action by the singular chains of the little 2-cubes operad. In this paper we give an affirmative answer to this question. We also show that the topological Hochschild cohomology spectrum of an associative ring spectrum has an action of an operad equivalent to the little 2-cubes.
