järjestysteoria
Järjestysteoria, also known as order theory, is a branch of mathematics that studies various kinds of mathematical structures called ordered structures. It is concerned with the properties of relations such as "less than or equal to" or "is a subset of". These relations are typically reflexive, antisymmetric, and transitive, properties that define a partial order.
The most fundamental concept in järjestysteoria is that of a partially ordered set, often denoted as a
Within järjestysteoria, specific types of ordered structures are studied. Lattices are a particularly important class of
Applications of järjestysteoria can be found in various fields, including computer science (e.g., in type theory
