On the Isomorphisms Between Certain Congruence Groups, II
Published online by Cambridge University Press: 20 November 2018
Extract
For integral domains of characteristic not 2, we prove here that the symplectic and unitary congruence groups are not isomorphic if the Witt indices are at least 3. This is Theorem 2.1; Theorem 3.3 describes the isomorphisms of unitary congruence groups.
