Determines conditions for bounded Engel identities in symmetric units of group rings over infinite fields.
Let G be a group and F an infinite field of characteristic p ≠ 2 . If either G is torsion, or p > 2 and G has only finitely many p -elements, we determine the conditions under which the symmetric units of the group ring FG , with respect to the classical involution, satisfy a bounded Engel identity.
