摘要

给出了3 × 3幂等矩阵在某些积分域上的行列式、迹和秩的刻画。重新考察了“每一个零清洗的3 × 3积分矩阵是交换的”的猜想。几个新的案例得到了证实。

3×3 idempotent matrices over some domains and a conjecture on nil-clean matrices

A characterization of the 3 × 3 idempotent matrices over some integral domains is given, in terms of determinant, trace and rank. The conjecture: every nil-clean 3 × 3 integral matrix is exchange, is revisited. Several new cases are proved.
