provectantn.

Brit.

/prə(ʊ)ˈvɛkt(ə)nt/, U.S.

/prəˈvɛkt(ə)nt/,

/proʊˈvɛkt(ə)nt/

Origin: A borrowing from Latin, combined with an English element. Etymons: Latin prōvect- , prōvehere , -ant suffix¹.

Etymology: < classical Latin prōvect-, past participial stem of prōvehere (see provect v.) + -ant suffix¹, after provector n.² Compare contraprovectant n.

Mathematics. Now rare.

An invariant (invariant n. 1a) considered as resulting from the action of a provector on a contravariant.

ΚΠ

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.

1908 Proc. Royal Soc. 1907–8 A. 80 152 All the operational processes.., including those which produce evectants, provectants, and emanants,..are included.
