Free subalgebras of division rings
Abstract:
\indent We report on recent work joint with Jason Bell. Makar-Limanov showed that the quotient division ring of the first Weyl algebra contains a copy of a free algebra on 2 generators. We prove the natural analog of this result for arbitrary iterated skew polynomial rings of fields.
