Similarly, the zero set of a (not identically zero) holomorphic function in C2is a one-dimensional complex variety, while the zero set of a holomorphic function in C1is a zero-dimensional variety (that is, a discrete set of points).

Web5 Sep 2024 · As \(\mathcal{O}_p\) is Noetherian, \(I_p(X)\) is finitely generated. Near each point \(p\) only finitely many functions are necessary to define a subvariety, that is, by an exercise above, those functions “cut out” the subvariety. When one says defining functions for a germ of a subvariety, one generally means that those functions generate the ideal, … Web24 Apr 2024 · Note. Theorem IV.3.7 allows us to factor analytic functions as given in the fol-lowing. Corollary IV.3.9. If f is analytic on an open connected set G and f is not identically zero then for each a ∈ G with f(a) = 0, there is n ∈ N and an analytic function g : G → C such that g(a) 6= 0 and f(z) = (z−a)ng(z) for all z ∈ G.
