WebDec 17, 2024 · Download PDF Abstract: Frobenius' Theorem states that the algebra of quaternions $\mathbb H$ is, besides the fields of real and complex numbers, the only finite-dimensional real division algebra. We first give a short elementary proof of this theorem, then characterize finite-dimensional real algebras that contain either a copy of $\mathbb … Webthe Frobenius element. Then we will use the Frobenius element to show the construction of Galois groups Sp and Ap for prime p, the irreducibility of cy-clotomic polynomials, and the signi cance of Chebotarev’s Density Theorem.
