Natural order on variant semigroup of transformation semigroup preserving equivalence relation

摘要: 在保等价变换半群上规定新的运算，通过此运算，得到保等价变换半群的变种半群.给出了此半群中自然偏序关系的定义，利用定义考察了半群中两个元素何时关于此偏序关系是相关的，并探讨了关于这个关系相容的元素，所得结果推广了保等价变换半群上的自然偏序关系.

Abstract: A new calculation on transformation semigroup preserving equivalence relation is defined and its variant semigroup derived. The definition of the natural order of the variant semigroup is given, and based on the definition, conditions that the two elements of the variant semigroup are related under the natural order are examined. Meanwhile, the elements about the natural order which are compatible are discussed. Then, the study of the natural order of transformation semigroup preserving equivalence relation is promoted.
