摘要:In this paper, we characterized the Green’s relation on ; the contraction mapping injective partial transformation semigroup on n-objects. Using two parameters. We found that the order of L-classes and are the same but is different.

摘要:Let $X_{n}$ be a finite set, $CT_{n}$ the semigroup of full contraction and $OCT_{n}$ order-preserving full contraction transformation semigroup of a finite set. In this paper the Local and global U-depth as well as the status of $OCT_{n}$ were investigated where U is the ge...
