Brauer Groups,aded field. This result is fundamental for the use of graded algebras to study division algebras over Henselian fields. An application is given to obtain a split exact sequence for the inertially split part of the Brauer group of a Henselian field. Another application of the theorem yields Witt’s de

Total Ramification, graded field (i.e., .. is separably closed), we prove a group isomorphism from .(.) to the part of . of torsion prime to . mapping ., where . is the canonical pairing induced by commutators. For . not inertially closed, this leads to a description of .(.)/..(.) as a subgroup of . determined by the

The Essential Dimension of Central Simple Algebras,hen in §. we sketch their method to obtain lower bounds on the essential .-dimension of central simple algebras. In the final §., we discuss consequences of these lower bounds for the decomposability of division algebras into tensor products of symbol algebras.

In addition, the use of valuation theory in reduced Whitehead group calculations (after Hazrat and Wadsworth) and in essential dimension computations (after Baek and Merkurjev) is showcased..The intended audience consists of graduate students and research mathematicians..
