Abstract

We study the action of the orthogonal group on the little n $n$ -disks operads. As an application we provide small models (over the reals) for the framed little n $n$ -disks operads. It follows in particular that the framed little n $n$ -disks operads are formal (over the reals) for n $n$ even and coformal for all n $n$ .

实际模型的框架小n$ n$ -磁盘操作
研究了正交群对小n$ n$ -盘操作数的作用。作为一个应用程序,我们为框定的小n$ n$ -disks操作提供了小模型(超过实数)。特别值得一提的是,对于n$ n$偶数,框定的小n$ n$盘操作符是形式的(在实数上),对于所有n$ n$都是共形的。

期刊介绍: The Journal of Topology publishes papers of high quality and significance in topology, geometry and adjacent areas of mathematics. Interesting, important and often unexpected links connect topology and geometry with many other parts of mathematics, and the editors welcome submissions on exciting new advances concerning such links, as well as those in the core subject areas of the journal. The Journal of Topology was founded in 2008. It is published quarterly with articles published individually online prior to appearing in a printed issue.
