WebFor the usual base for this topology, every finite intersection of basic open sets is a basic open set. The Zariski topology of is the topology that has the algebraic sets as closed sets. It has a base formed by the set complements of algebraic hypersurfaces. WebIn class, we showed that open sets are closed under the operations of arbitrary union and finite intersection. When we stated this theorem, I claimed that all open sets can be obtained by taking unions of open intervals. Upon further reflection, I think you can prove this: Let U={(a,b)∣a,b∈R} denote the collection of all open intervals 1 in R.

Web2 can be written as finite intersections of irreducible ideals inR. However, this immediately implies that Jcan be also written as a finite intersection of irreducible ideals in R, contradicting that Jbelongs to S.

[topology:closediii] If $E_1, E_2, \ldots, E_k$ are closed then \[\bigcup_{j=1}^k E_j\] is also closed. That is, finite union of closed sets is closed. We have not yet shown that the open ball is open and the closed ball is closed. Let us show this fact now to justify the terminology.
