半星运算的谱空间

Spectral spaces of semistar operations

Carmelo A. Finocchiaro, Marco Fontana, Dario Spirito

摘要:

我们调查,从拓扑的角度来看,类的谱半星运算和EAB半星运算,以下方法最近介绍了Finocchiaro和Finocchiaro-Spirito在\cite{Fi, FiSp}。我们表明,在这两种情况下,有限型操作的子空间是谱空间的意义上的Hochster,而且,有一个特殊的类的覆盖环严格连接到每一个两种类型的集合的半星操作。我们还证明了稳定半星运算空间同胚的Gabriel-Popescu局部化系统的空间,赋予了一个Zurkiki-like拓扑,推广到拓扑水平的Fontana-Huckaba在\cite{fohu}中建立的结果。作为一个副作用,我们得到了有限型局部化系统的空间也是一个谱空间。最后,我们证明了半星运算集上的Zapriki拓扑与最近由B. Olberding \cite{ol, olb_noeth}。

英文摘要:

We investigate, from a topological point of view, the classes of spectral semistar operations and of eab semistar operations, following methods recently introduced by Finocchiaro and Finocchiaro-Spirito in \cite{Fi, FiSp}. We show that, in both cases, the subspaces of finite type operations are spectral spaces in the sense of Hochster and, moreover, that there is a distinguished class of overrings strictly connected to each of the two types of collections of semistar operations. We also prove that the space of stable semistar operations is homeomorphic to the space of Gabriel-Popescu localizing systems, endowed with a Zariski-like topology, extending to the topological level a result established by Fontana-Huckaba in \cite{fohu}. As a side effect, we obtain that the space of localizing systems of finite type is also a spectral space. Finally, we show that the Zariski topology on the set of semistar operations is the same as the $b$-topology defined recently by B. Olberding \cite{ol, olb_noeth}.
