Equivalent Conditions for (Weak) Corestriction Principle for Non-Abelian \'Etale Cohomology of Group Schemes

Nguyen Quoc Thang

Abstract.  We introduce the notion of (Weak) Corestriction Principle and prove some equivalent relations between the validity of this principle for various connecting maps in non-abelian \'etale cohomology.

2000 Mathematics Subject Classification: {Primary 11G72; Secondary 18G50, 20G10.

Keywords: Corestriction maps, norm maps, non-abelian \'etale cohomology.
