ON SEMIGENERIC TAMENESS AND BASE FIELD EXTENSION
Published online by Cambridge University Press: 21 July 2015
Abstract
The notions of central endolength and semigeneric tameness are introduced, and their behaviour under base field extension for finite-dimensional algebras over perfect fields are analysed. For k a perfect field, K an algebraic closure and Λ a finite-dimensional k-algebra, here there is a proof that Λ is semigenerically tame if and only if Λ ⊗kK is tame.
