摘要：
We prove that trace 1 matrices over principal ideal domains are exchange and characterize 2 x 2 exchange matrices over commutative domains. In addition, we emphasize large dasses of not exchange 2 x 2 and 3 x 3 integral matrices. We prove that trace 1 matrices over principal ideal domains are exchange and characterize 2 x 2 exchange matrices over commutative domains. In addition, we emphasize large classes of not exchange 2 x 2 and 3 x 3 integral matrices.
