† provectorn.¹

Origin: Formed within English, by derivation. Etymons: pro- prefix², vector n.

Etymology: < pro- prefix² + vector n. Compare transvector n.

Mathematics. Obsolete. rare.

A vector which is to be added to another.

provectorn.²

Brit.

/prə(ʊ)ˈvɛktə/, U.S.

/proʊˈvɛktər/

Origin: A borrowing from Latin, combined with an English element. Etymons: Latin prōvect- , prōvehere , -or suffix.

Etymology: < classical Latin prōvect-, past participial stem of prōvehere (see provect v.) + -or suffix. Compare provectant n. and contraprovector n.

Mathematics. Now rare.

A differential operator (of order greater than one) acting on a function of several variables, having the form of a quantic in which the variables are replaced by first-order differential operators.

1858 A. Cayley Coll. Math. Papers II. 514 The Provector operating upon any contravariant gives rise to a contravariant, which may of course be an invariant. Any such contravariant, or rather such contravariant considered as so generated, may be termed a Provectant.

1909 N.E.D. at Provectant A covariant considered as the resultant of the operation of a provector on a contravariant.
