Finite verbs play a particularly important role in syntactic analyses of sentence structure. In many phrase structure grammars for instance those that build on the X-bar schema, the finite verb is the head of the finite verb phrase and so it is the head of the entire sentence.
Any subset of a finite set is finite. The set of values of a function when applied to elements of a finite set is finite. All finite sets are countable, but not all countable sets are finite. (Some authors, however, use "countable" to mean "countably infinite", so do not consider finite sets to be countable.) The free semilattice over a finite ...
In mathematics, a set is countable if either it is finite or it can be made in one to one correspondence with the set of natural numbers. [a] Equivalently, a set is countable if there exists an injective function from it into the natural numbers; this means that each element in the set may be associated to a unique natural number, or that the elements of the set can be counted one at a time ...
The definition of a finite set is given independently of natural numbers: [3] Definition: A set is finite if and only if any non empty family of its subsets has a minimal element for the inclusion order. Definition: a cardinal n is a natural number if and only if there exists a finite set of which the cardinal is n. 0 = Card (∅)
Finite may refer to: Finite set , a set whose cardinality (number of elements) is some natural number Finite verb , a verb form that has a subject, usually being inflected or marked for person and/or tense or aspect
The finite intersection property, abbreviated FIP, says that the intersection of any finite number of elements of a set is non-empty first 1. A set of first category is the same as a meager set: one that is the union of a countable number of nowhere-dense sets. 2. An ordinal of the first class is a finite ordinal 3.
As are the set of real numbers or the set of natural numbers: whenever x > y and y > z, then also x > z whenever x ≥ y and y ≥ z, then also x ≥ z whenever x = y and y = z, then also x = z. More examples of transitive relations: "is a subset of" (set inclusion, a relation on sets) "divides" (divisibility, a relation on natural numbers)
This article lists mathematical properties and laws of sets, involving 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.
