12 % The fraction field of its argument, an integral domain. The name
13 % "Frac" was chosen here instead of "Quot" because the latter
14 % corresponds to the term "quotient field," which can be mistaken in
15 % some cases for... a quotient field (something mod something).
16 \newcommand*
{\Frac}[1]{\operatorname{Frac
}\of{{#1}}}
18 % The polynomial ring whose underlying commutative ring of
19 % coefficients is the first argument and whose indeterminates (a
20 % comma-separated list) are the second argumnt.
21 \newcommand*
{\polyring}[2]{{#1}\left[{#2}\right]}
