Certain simple maximal subfields in division rings. (English) Zbl 07144874

Summary: 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 \(a\in D^{(n)}\), 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 \(D\).
