This chapter explains partial orders and lattices. Lattices are defined in terms of two operations analogous to set intersection and union. These induce a partial order analogous to subset ordering. Lattices have application both to explicit definition and to the development of Boolean algebra. ...

In the third section, we describe a number of duality theorems which havethe common thread that they describe dualities between categories of partiallyordered sets, on the one hand, and categories of lattices, on the other. We startwith the duality between the category of sets and functions ...

Complete lattices must not be confused with complete partial orders (cpos), which constitute a strictly more general class of partially ordered sets. 完全格一定不能混淆于完全偏序(cpo),它构成严格的更加一般的一个偏序集合类别。 LASER-wikipedia2 For example, the ideal completion of a given parti...

In [19], we introduced five new order relations on partial partitions, obtained by restricting the standard order; they do not constitute lattices; then, we showed by combinatorial methods that in the finite case, the Jordan–Hölder theorem holds for the standard order and these five orders....
We study the lattice structure and we give properties of the down-sets. We prove that the down-set of B ordered by the core partial order and by the star partial order are sublattices of the down-set ordered by the left star partial order. We analize the existence of supremum and ...
Related notions such as quasiorders, weak, and linear orders are introduced. Semiorders and interval orders are discussed with particular emphasis on their numerical representations. The order theoretic and algebraic properties of lattices are summarized. The question of the possibility of linear ...
