Longman Dictionary of Contemporary English
PRO or Pro may refer to:
PRO (category theory)
In category theory, a PRO is a strict monoidal category whose objects are the natural numbers (including zero), and whose tensor product is given on objects by the addition on numbers.
Some examples of PROs:
- the discrete category N of natural numbers,
- the category FinSet of natural numbers and functions between them,
- the category Bij of natural numbers and bijections,
- the category '''Bij '''of natural numbers, equipped with the braid group ''B ''as the automorphisms of each ''n ''(and no other morphisms).
- the category Inj of natural numbers and injections,
- the simplex category Δ of natural numbers and monotonic functions.
The name PRO is an abbreviation of "PROduct category". PROBs and PROPs are defined similarly with the additional requirement for the category to be braided, and to have a symmetry (that is, a permutation), respectively. All of the examples above are PROPs, except for the simplex category and Bij; the latter is a '''PROB '''but not a PROP, and the former is not even a PROB.
In generative linguistics, PRO (called "big PRO", distinct from pro, "small pro" or " little pro") is a pronominal determiner phrase (DP) without phonological content. As such, it is part of the set of empty categories. The null pronoun PRO is postulated in the subject position of non-finite clauses. One property of PRO is that, when it occurs in a non-finite complement clause, it can be bound by the main clause subject ("subject control") or the main clause object ("object control"). The presence of PRO in non-finite clauses lacking overt subjects allows a principled solution for problems relating to Binding Theory.
Within Government and Binding theory, the existence and distribution of PRO followed from the PRO Theorem, which states that PRO may not be governed. More recent analyses have abandoned the PRO Theorem. Instead, PRO is taken to be in complementary distribution with overt subjects because it is the only item that is able to carry null case which is checked for by non-finite Tense Markers (T), for example the English to in control infinitives.
