拓扑霍赫希尔德同调的Ausoni-Bokstedt对偶

Ausoni-Bokstedt duality for topological Hochschild homology

J. P. C. Greenlees

摘要:

我们考虑了拓扑霍赫希尔德同调的Gorenstein条件,并证明了它经常成立。更精确地说,如果R是一个交换环谱,并且R->k是一个到特征为p的域的环映射,那么,如果k作为一个R-模是小的,THH(R;k)是Dwyer-Greenlees-Iyengar意义下的Gorenstein。特别是,这保持如果R是一个(传统的)正则局部环与剩余域k的特征p.仅使用Bokstedt的计算THH(k),这给出了一个非计算证明的对偶观察计算Bokstedt,McClure-Staffeldt,Ausoni-Rognes,Ausoni,Lindenstrauss-Madsen,Angeltweit-Rognes和其他人。Dundas的一个引理表明THH(R;k)是非常可计算的。

英文摘要:

We consider the Gorenstein condition for topological Hochschild homology, and show that it holds remarkably often. More precisely, if R is a commutative ring spectrum and and R----->k is a ring map to a field of characteristic p then, provided k is small as an R-module, THH(R;k) is Gorenstein in the sense of Dwyer-Greenlees-Iyengar. In particular, this holds if R is a (conventional) regular local ring with residue field k of characteristic p. Using only Bokstedt's calculation of THH(k), this gives a non-calculational proof of dualities observed in calculations by Bokstedt, McClure-Staffeldt, Ausoni-Rognes, Ausoni, Lindenstrauss-Madsen, Angeltweit-Rognes and others. A lemma of Dundas shows that THH(R;k) is remarkably computable.
