# Set System

(Redirected from set theory)

A Set System is a Formal System for sets and Set Operations.

**AKA:**Set Theory, Set Formal System, Formal Set System, Set Algebra, Algebra of Sets, [math](V,\mathcal{I})[/math].**Context:**- It must include Set Operations (that can be constrained by Set Axioms).
- It must include a Set Formal Language.
- It can range from being an Independent Set System to being a Dependent System System.

**Counter-Example(s):****See:**Multiset, Rough Set Theory, Infinite Set, Empty Set, Countable Set, Matroid, Discrete Mathematics.

**algebra of sets**defines the properties and laws of sets, the set-theoretic operations of union, intersection, and complementation and the relations of set equality and set inclusion. It also provides systematic procedures for evaluating expressions, and performing calculations, involving these operations and relations.Any set of sets closed under the set-theoretic operations forms a Boolean algebra with the join operator being
