UNRAMIFIED SCALAR EXTENSIONS OF GRADED DIVISION ALGEBRAS
Hwang, Yoon Sung;

Abstract
Let E be a graded central division algebra (GCDA) over a grade field R. Let S be an unramified graded field extension of R. We describe the grading on the underlying GCDA E' of $\small{E{\otimes}_RS}$ which is analogous to the valuation on a tame division algebra over Henselian valued field.
