| In this paper,some relevant conclusions are got by the studied of the subsemigroup lattice of regular semigroups.We acquired the sufficient and necessary conditions for the full subsemigroup form a chain of regular semigroups,and the orthodox semigroups.And more,we studied the full regular subsemigroup lattice of orthodox semigroups,and some characterizations of lattice isomorphisms are given.In the last,we obtained some properties of the subsemigroup of E-unitary inverse semigroups. |
