A note on multiplicative commutators of division rings

Rings and Algebras 2017-06-27 v1

Abstract

We give an example of a division ring DD whose multiplicative commutator subgroup does not generate DD as a vector space over its centre, thus disproving the conjecture posed in the paper "Vector space generated by the multiplicative commutators of a division ring, J. Algebra Appl. 12 (2013), no. 8".
