WebChoose an affine neighbourhood U = \mathop {\mathrm {Spec}} (A) of x. Then \dim _ x (X) = \dim _ x (U). Hence we reduce to the affine case, which is Algebra, Lemma 10.114.6. Proof of ( 3 ). It suffices to show that any two nonempty affine opens U, U' \subset X have the same dimension (any finite chain of irreducible subsets meets an affine open). http://sporadic.stanford.edu/conformal/lecture6.pdf
