系统地给出了分级Azumaya代数的一些基本性质。在这里,分级是由一个任意加性群来指示的,分级Azumaya代数的概念是相对于交换因子的选择的。我们还建立了两个推广了Skolem-Noether定理的精确序列。
Some basic properties of graded Azumaya algebras are given systematically.Here, the grading is indexed by an arbitrary additive group and the notion of a graded Azumaya algebra is relativeto a choice of a commutation factor.We also establishtwo exact sequences which generalize the Skolem-Noether theorem.
