素数为2时的乘法2-上圈

Multiplicative 2-cocycles at the prime 2

Adam Hughes, JohnMark Lau, Eric Peterson

摘要:

利用对称可加2-上圈的分类结果,我们收集了关于形式群的Lubin-Tate上同调的各种事实来计算对称可乘2-上圈方案的2-准素分支.该方案对某些高度对称的多重扩张进行了分类,正如Mumford或Breen所研究的那样。这种计算的低阶版本以前已经通过Ando、Hopkins和Strickland的sigma定向在同伦理论中找到了应用,并且完整的计算反映了在同伦类型的连接K理论中发现的某些结构。这篇论文已经完全重写了第一稿,包括对主要结果的声明的更正。

英文摘要:

Using a previous classification result on symmetric additive 2-cocycles, we collect a variety of facts about the Lubin-Tate cohomology of formal groups to compute the 2-primary component of the scheme of symmetric multiplicative 2-cocycles. This scheme classifies certain kinds of highly symmetric multiextensions, as studied in general by Mumford or Breen. A low-order version of this computation has previously found application in homotopy theory through the sigma-orientation of Ando, Hopkins, and Strickland, and the complete computation is reflective of certain structure found in the homotopy type of connective K-theory. This paper has been completely rewritten from its first posted draft, including a correction of the statement of the main result.
