quartinvariantn.

Brit.

/ˌkwɔːtɪnˈvɛːrɪənt/, U.S.

/ˌkwɔrdɪnˈvɛriənt/,

/ˌkwɔrdᵻnˈvɛriənt/

Origin: Formed within English, by compounding. Etymons: quartic n., invariant n.

Etymology: < quart- (in quartic n.) + invariant n. Compare sextinvariant n.

Mathematics.

An invariant of the fourth degree.

ΚΠ

1856 Philos. Trans. (Royal Soc.) 146 632 The sextinvariant may be thus represented by means of a determinant of the sixth order and of the quadrinvariant and quartinvariant.

1889 Amer. Jrnl. Math. 12 28 The value of the quartinvariant S.

1939 Duke Math. Jrnl. 5 560 It is of interest to calculate the quartinvariant S and the sextinvariant T for the cubic X(x) = 0.
