"Webb1 aug. 2024 · Solution 1. You have a tower of extensions K ⊆ L ⊆ L ( α) with α separable and algebraic over K from which it follows that L ( α) / K is a finite separable extension. It now follows that L / K is finite and separable and so by the primitive element theorem is simple. Added for OP: Theorem. " - Simple extension theorem

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. WebbLast time, we introduced automorphisms of a eld extension K=F (ring isomorphisms of K with itself that x F) and characterized automorphisms of simple extensions: Theorem (Automorphisms of Simple Algebraic Extensions) Suppose is algebraic over F with minimal polynomial m(x), and K = F( ): then for any ˙2Aut(K=F), ˙( ) is also a root of m(x) in K.

Webb14 dec. 2024 · Gödel’s famous incompleteness theorem showed us that there is a statement in basic arithmetic that is true but can never be proven with basic arithmetic. But that is just the beginning of the story. There are more true but unprovable, or even able to be expressed, statements than we can possibly imagine, argues Noson S. Yanofsky.
