| | 06: Order, lattices, ordered algebraic structures |
 | | Ordered sets, or lattices, give a uniform structure to, for example, the set of subfields of a field. |
 | | Linear orderings especially on infinite sets is the study of Ordinals in Set Theory; these are traditionally considered in 03: Mathematical Logic, especially 03G: Algebraic Logic. |
 | | Ordered sets may be viewed as topological spaces; see 54: General Topology, especially 54F05: Ordered topological spaces, for more detail. |
