On index-exponent relations over Henselian fields with local residue fields

Rings and Algebras 2019-02-20 v7

Abstract

Let pp be a prime number and (K,v)(K, v) a Henselian valued field with a residue field K^\widehat K. This paper determines the Brauer pp-dimension of KK, in case pchar(K^)p \neq {\rm char}(\widehat K) and K^\widehat K is a pp-quasilocal field properly included in its maximal pp-extension. When K^\widehat K is a local field, it describes index-exponent pairs of central division KK-algebras of pp-primary degrees. The same goal is achieved, if (K,v)(K, v) is maximally complete, char(K)=p(K) = p and K^\widehat K is local.
