  Ordered structures have been increasingly recognized in recent years due to an explosion of interest in theoretical computer science and all areas of discrete mathematics. This book covers areas such as ordered sets and lattices. A key feature of ordered sets, one which is emphasized in the text, is that they can be represented  › Books › Science & Math › Mathematics.   The study of inductive and coinductive types (like finite lists and streams, respectively) is usually conducted within the framework of category theory, which to all intents and purposes is a theory of sets and functions between ~psarb2/papers/

Nets are generalisations of sequences involving possibly uncountable index sets; this notion was introduced about a century ago by Moore and Smith, together with the generalisation to nets of various basic theorems of analysis due to Bolzano-Weierstrass, Dini, Arzelà, and others.

We study order-theoretical, algebraic and topological aspects of compact generation in ordered sets. Today, algebraic ordered sets (a natural generalization of algebraic lattices) have their place not only in classical mathematical disciplines like algebra and   is a partially ordered set (poset) closed under one of two binary operations, either supremum (join) or infimum (meet).

Hence we speak of either a join-semilattice or a meet-semilattice. If an ordered set is both a meet- and join-semilattice, it is also a lattice.

In this paper, we generalize a series of research work about convexity on classical partially ordered sets to fuzzy partially ordered sets (L-posets).Taking a complete Heyting algebra as the truth value structure, we propose an L-ordered L-convex structure on an L-poset and give its corresponding L-convex characterize the L-ordered L-convex sets in terms of four kinds of cut
