WebDeﬁnition. Let f : A→ Bbe a ring-homomorphism of ﬁnite type of locally Noetherian rings. The homomorphism fis called unramiﬁed if PBP = (P∩A)BP and k(P) = BP/PBP is a ﬁnite separable ﬁeld extension of k(P∩P) = AP∩P/(P∩ A)AP∩A for all prime ideal P of B. The homomorphism f is called etale if f is unramiﬁed and ﬂat ... WebA nation as a topological space. We define the topology in the nation X, which with it we can study the connectivity, separability, compactness, and continuity of functions between nations. The topology that we construct comprises of decision spaces in X. We will call this topology a representative topology.
