Certain simple maximal subfields in division rings

Abstract: Let D be a division ring finite dimensional over its center F . The goal of this paper is to prove that for any positive integer n there exists a ∈ D (n) , the n-th multiplicative derived subgroup, such that F (a) is a maximal subfield of D. We also show that a single depth-n iterated additive commutator would generate a maximal subfield of D.

“…There are still other evidences to show how one can rely on maximal subfields to deduce further information about the whole division ring [4]. In particular, according to the Skolem-Noether Theorem [11, P. 93] we know that if A is a centrally finite simple F -algebra, then every F -automorphism of A is inner.…”
