WebA Noetherian scheme has a finite number of irreducible components. Proof. The underlying topological space of a Noetherian scheme is Noetherian (Lemma 28.5.5) and we conclude because a Noetherian topological space has only finitely many irreducible components (Topology, Lemma 5.9.2). $\square$ Lemma 28.5.8.
