(qq) C_DD2r + l; or +1 C_DD2, +1. Same reason, Sichuan , D, +, m also has this property . Theorem 3DD2r + l, Sichuan , Dr +2,2 r +2 are 0, a maximal subsemigroup. Proof: One of VEJ . DD2. , It certainly has ∈ Research +1). By the Theorem 2 , or + . DD2, and Sichuan contains idempotents [p +1] or contain idempotent ... [p +1 P], by Lemma 1 , a = L = Lq or +1 = on ,tory burch, d = Lq. Also according to Theorem 2 , feet (q1) or foot (q a 1, q) ~ _DD2r + l Xi Jj What , £ gn feet (g. port +1) = [q-* q +1] or £ n mouth Feet (oral _1.q) = [g_ + g -1 ], by Lemma 2 , P a 1 = LqR ( port A 1, q) u {0} or p- 1 = Lq foot (q, q +1) u {0}. 4 Zhang Chuanjun , Lin Ping Feng, Mamin Yao : Finite preserving transformation semigroups Maximal subsemigroups 0 Lemma 4, therefore, according to knowledge, a collection of DD: ... u {} generation 0, ie DD: River is a very 0 Large subsemigroups . Same reason , ..., DU2 Ⅲ, UD: m is 0, the maximal semigroups .
