微分Brauer幺半群

Differential Brauer Monoids

Andy R. Magid

摘要:

定义了微分交换环R的微分Brauer幺半群.它的元素是具有张量积运算的微分Azumaya R代数的同构类,条件是两个这样的代数等价,如果它们上的矩阵代数是微分同构的.鲍尔幺半群是一个群,没有微分要求也是一样的。微分Brauer幺半群是由R的Brauer幺半群及其常数环和其基础Azumaya代数是矩阵环的子幺半群确定的。

英文摘要:

The differential Brauer monoid of a differential commutative ring R s defined. Its elements are the isomorphism classes of differential Azumaya R algebras with operation from tensor product subject to the relation that two such algebras are equivalent if matrix algebras over them are differentially isomorphic. The Bauer monoid, which is a group, is the same thing without the differential requirement. The differential Brauer monoid is then determined from the Brauer monoids of R and its ring of constants and the submonoid whose underlying Azumaya algebras are matrix rings.
