摘要
设集合I,Λ是任意的非空集合.当θ=Λ'×I■Λ×I时,本文获得了半群Pθ(I×Λ)的非可解元和不可约生成集,并且给出了半群Pθ(I×Λ)的Green-关系,最后讨论了半群Pθ(I×Λ)的一些特殊计数.
Let I,A be two arbitrary nonempty sets. Where θ=∧'×I, the non-solvable elements and the irreducible generating sets of the semigroup Pθ(I×∧) are established; the Green's relations of the semigroup Pθ(I×∧)are obtained; some specific counts of the semigroup Pθ(I×∧) are discussed.
