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.

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. WebbHowever, the equipartition theorem also shows that if a degree of freedom x contributes only a multiple of x s (for a fixed real number s) to the energy, then in thermal equilibrium the average energy of that part is k B T/s. There is a simple application of this extension to the sedimentation of particles under gravity.
