The Boolean operator of complementation is not like negation in the sense of propositional logic. It does not produce Not-P, to be interpreted semantically as the negation of P, meaning that if P is true, then Not-P is false, and if P is false, then Not-P is true. The symbol ‘P...
whereb(v1,…,vn)is a Boolean function ofnvariables. The mapping1S↦ϕb(1S)is a nonlinear shift-invariant operator for binary signals, called aBoolean filterorBoolean operator. This has a unique correspondence with aTI setoperatorΦbby replacing input and output binary signals with sets: ...
Boolean operators are used in computer programming, mathematical formulas andalgorithms. They are often used to refine web searches. Using a Boolean operator as a conjunction between two keywords in a web search either combines or excludes them, thus generating more focused and useful results. The ...
if a person is searching for a document that contains both the words “Boolean” and “computer science”, a search phrase might be created using the Boolean operator “and”: “Boolean and computer science.” In this case, the operator “and” tells the search engine that it ...

The dual Boolean function b∗ will generate the dual set operator Φb∗. Assume henceforth that b is increasing; then, both Φb and its dual are TI, increasing, and u.s.c. discrete set operators on P(Zm). Hence, by Theorem 21, Φb can be represented as the union of erosions ...
