Bunina, D. Trushin, M. Tsvetkov] In this paper, we construct noncommutative algebras over a square-closed field such that the unitary linear groups over these algebras decompose to nontrivial free products. In particular, we give an example in which the elementary unitary subgroup belongs to one of these factors. Springer Science+Business Media New York, 2015 Bunina E.
