摘要

在本文中,我们分类了在Steenrod操作下闭合的h(BA4;F2)和Dickson代数中h(BSO(3);F2)的参数理想。因此,我们得到了尺寸n,m的限制,A4(和SO(3))可以在Sn×Sm上自由活动。

Steenrod closed parameter ideals in the mod-2 cohomology of A4 and SO(3)
In this paper, we classify the parameter ideals in H(BA4;F2) and in the Dickson algebra H(BSO(3);F2) that are closed under Steenrod operations. Consequently, we obtain restrictions on the dimensions n,m for which A4 (and SO(3)) can act freely on Sn×Sm.

期刊介绍: The Journal of Pure and Applied Algebra concentrates on that part of algebra likely to be of general mathematical interest: algebraic results with immediate applications, and the development of algebraic theories of sufficiently general relevance to allow for future applications.
