拟合理性与prounipotent交叉模
Quasirationality and prounipotent crossed modules
摘要:
研究了(pro- $p$)群的拟有理表示($QR$ -表示).这种表示特别包括离散群及其子表示的非球面表示和具有单一定义关系的前$p$群。使用$QR$ -演示文稿的图式化,我们回答了J. P. Serre关于单关系元亲$p$群的问题。
英文摘要:
Quasirational presentations ($QR$-presentations) of (pro-$p$)groups are studied. Such presentations include, in particular, aspherical presentations of discrete groups and their subpresentations and pro-$p$-groups with a single defining relation. Using schematization of $QR$-presentations we answer a variation of J.-P. Serre's question on one-relator pro-$p$-groups.
