WebbFor a bounded countably additive function, the Carath eodory extension theorem states the following.1 Theorem 2 (Carath eodory extension theorem). Suppose that Xis a nonempty set, that S is a semiring on X, and that 0: S ![0;1] is countably additive. 1Ren e L. Schilling, Measures, Integrals and Martingales, p. 37, Theorem 6.1. WebbIn field theory, the primitive element theorem or Artin's theorem on primitive elements is a result characterizing the finite degree field extensions that possess a primitive element, or simple extensions. It says that a finite extension is simple if and only if there are only finitely many intermediate fields.

WebbMarkov chain [Dur19, Section 5.2] using the Kolmogorov extension theorem. In this note, we provide a proof of the Kolmogorov extension theorem based on the simple, but perhaps not widely known observation that R and the product measurable space 2N are Borel isomorphic. (We denote by 2 the discrete space f0;1g.) By a Borel isomorphism we mean … WebbIn the correspondence, normal extensions correspond to normal subgroups. In the above example, all subgroups are normal and the extensions are normal. We’ll also prove the Primitive Element Theorem, which in the context of nite extensions of Q, tells us that they are necessarily of the form Q( ) for some , e.g. Q(i; p 2) (or Q(i+ p 2)).

In field theory, the primitive element theorem is a result characterizing the finite degree field extensions that can be generated by a single element. Such a generating element is called a primitive element of the field extension, and the extension is called a simple extension in this case.
