| Abstract: |
| We study E-inversive semigroups of N(S, ∗, δ, 0) on N(2, 2, 2, 0) algebra. Using the properties of idempotents element, weak inverse element and middle unit, and congruence relations, we obtain the following results:if the idempotents set of N(2, 2, 0) algebra is nonempty, then its two dual semigroups (S, ∗) and (S, ∆) of N(2, 2, 0) algebra are E-inversive semigroups. Moreover, right adjoint non-zero divisor of element a on semigroup (S, ∗) of N(2, 2, 0) algebra is unique and is weak inverse of a. Some other conclusions are also discussed, which further characterize structure of N(2, 2, 0) algebra. |
