研究了*-λ-子半环,它是一类特殊的*-λ-半环,得出一些新的结果,并证明了若S是*-λ-半环,则对任意的整数n≥0,S上的n阶上(下)三角矩阵的集合也是*-λ-半环。
*-λ-subsemiring was studied, which is a special case of *-λ-semirings, and some new results are gotten. Meanwhile we proved that if it is a *-λ-semiring,for any integer n, the set of n -order upper(lower) triangular matrix overs is also a *-λ-semiring.
