在最近的工作中,Hess和Shipley[18]定义了余代数的拓扑余Hochschild同调理论(CoTHH)。在本文中,我们开发了计算工具来研究这一新理论。特别地,我们证明了微分分次余代数在无余项情形下的Hochschild-Kostant-Rosenberg型定理。我们还发展了一个cobökstedt谱序列来计算余代数谱的coTHH的同调。我们在这个谱序列上使用余代数结构来产生几次计算。
In recent work, Hess and Shipley [18] defined a theory of topological coHochschild homology (coTHH) for coalgebras. In this paper we develop computational tools to study this new theory. In particular, we prove a Hochschild–Kostant–Rosenberg type theorem in the cofree case for differential graded coalgebras. We also develop a coBökstedt spectral sequence to compute the homology of coTHH for coalgebra spectra. We use a coalgebra structure on this spectral sequence to produce several computations.
