摘要
Let D be a division algebra algebraic over its centre F. Given a (Krull) valuation upsilon on F, denote by V its valuation ring. It is shown that upsilon extends to a valuation on D if and only if (i) upsilon extends uniquely to each commutative subfield K of D with dim(F) K < infinity, (ii) Z(D') subset-of V*.
