Order-A Journal on the Theory of Ordered Sets and its Applications《序:有序集理论及其应用杂志》(一年3期). Order presents the most original and innovative research on ordered structures and the use of order-theoretic methods in graph theory and combinatorics, lattice theory and algebra, set theory and relational structures, and the theory of computing. In each of these categories, we seek submissions that make significant use of orderings to study mathematical structures and processes. The interplay of order and combinatorics is of particular interest, as are the application of order-theoretic tools to algorithms in discrete mathematics and computing. Articles on both finite and infinite order theory are welcome.
