This is one part of the main theorem of Galois Theory. First, however, we shall list some formal properties of the two operations we have described relating groups to eld extensions. Theorem. Webb29 nov. 2024 · We provide new simple proofs of the Kolmogorov extension theorem and Prokhorovs' theorem. The proof of the Kolmogorov extension theorem is based on the simple observation that and the product measurable space are Borel isomorphic. To show Prokhorov's theorem, we observe that we can assume that the underlying space is .
