完全对称商环

Perfect Symmetric Rings of Quotients

Lia Vas

摘要:

右理想的完全Gabriel滤子及其相应的右幂元环具有理想的特征,即每个幂元模都仅由右幂元环决定.另一方面,对称同分环具有模仿交换情形的对称性。在本文中,我们研究了结合这两个理想性质的等价环。定义了右完满环和右完全Gabriel滤子的对称形式--完全对称环和完全对称Gabriel滤子,并研究了它们的性质.然后证明了全右子环的标准构造可以适用于最大完全对称子环--全对称子环的构造。我们还证明了Morita的全右等价环的构造可以适用于全对称等价环的构造。

英文摘要:

Perfect Gabriel filters of right ideals and their corresponding right rings of quotients have the desirable feature that every module of quotients is determined solely by the right ring of quotients. On the other hand, symmetric rings of quotients have a symmetry that mimics the commutative case. In this paper, we study rings of quotients that combine these two desirable properties. We define the symmetric versions of a right perfect ring of quotients and a right perfect Gabriel filter -- the perfect symmetric ring of quotients and the perfect symmetric Gabriel filter and study their properties. Then we prove that the standard construction of the total right ring of quotients can be adapted to the construction of the largest perfect symmetric ring of quotients -- the total symmetric ring of quotients. We also demonstrate that Morita's construction of the total right ring of quotients can be adapted to the construction of the total symmetric ring of quotients.
