Let (B, ϑ) be a commutative Euclidean ring and let σ be an involution on B with fixed ring A such that for a1, a2 in A with a1+a2≠ 0, ϑ(a1+a2)≤ Max (ϑ(a1),ϑ(a2)} It was shown in [5] that any 2 x 2 non-singular Hermitian matrix over 5(w.r.t. σ) is diagonalisable.

Abstract


Let (B, ϑ) be a commutative Euclidean ring and let σ be an involution on B with fixed ring A such that for a1, a2 in A with a1+a2≠ 0, ϑ(a1+a2)≤ Max (ϑ(a1),ϑ(a2)} It was shown in [5] that any 2 x 2 non-singular Hermitian matrix over 5(w.r.t. σ) is diagonalisable.
