Isomorphisms of unitary groups over associative rings (Q1059156)

Automorphisms of unitary linear groups U(n,\(\Lambda\),q) over the ring \(\Lambda\) are found to be standard on an elementary unitary subgroup in the case when the hyperbolic rank of the form q is strictly greater than one and \(n\geq 5\) (for a commutative ring, \(n\geq 4)\).
