Computing the congruence class of some left restriction semigroups in โ๐ด_X
Journal of Semigroup Theory and Applications ยท 2020
In this paper, we present some examples of left restriction semigroups embedded in the partial transformation โ๐ด_X. Also, we compute and enumerates the congruence-class ~R and the semilattice of idempotents E_X inherent in the examples generated.
