31 results about "Field of sets" patented technology

In mathematics a field of sets is a pair 〈X,F〉 where X is a set and F is an algebra over X i.e., a non-empty subset of the power set of X closed under the intersection and union of pairs of sets and under complements of individual sets. In other words, F forms a subalgebra of the power set Boolean algebra of X. (Many authors refer to F itself as a field of sets.) Elements of X are called points and those of F are called complexes and are said to be the admissible sets of X. Fields of sets should not be confused with fields in ring theory nor with fields in physics.
