    • n conjugation In Hebrew and other Semitic languages, one of several groups of inflections normally formed from the same verb, and expressing a modification of meaning analogous to that found in certain classes of derivative verbs in Indo-European languages, or to the voices of these. [The latin conjugatio is a translation of the Greek συζυγία, properly derivation, including inflection as well as formation of new words, but afterward limited to the inflection of verbs, which had previously been called simply inflection, or infection of verbs (κλίσις ρ)ημάτων dedinatio verborum).]
    • n conjugation A union or coupling; a combination of two or more individuals. [Obsolete except in specific use. See 4.]
    • n conjugation In biol, a union of two distinct cells for reproduction; a temporary or permanent growing together of two or more individuals or cells, with fusion of their plasmodic substance, as a means of reproduction by germs or spores, or a means of renewing individual capacity to multiply by fission. It is a kind of copulation of the entire bodies of different individuals or cells, with the formation of new nuclei or other form-elements, preparatory to the development of new individuals. It is also called zygosis, and the resulting blended organism is ealled a zygote or zygospore. The process occurs only in the lower animals and plants, among many of which it is an ordinary mode of reproduction. It is very common in protozoans, and has been observed in certain worms. (See Dipiozoon.) A permanent fusion takes place in the unicellular alagœ Diatomaceœ and Desmidiaceœ by the union of the contents of two separate cells; in the Zygnemaceæ and Mesocarpeæ, by that of two cells of different filaments or of the same filament; and in the Zoösporeæ, by that of zoöspores from different mother-cells. The result of the union in each case is called zygospore; the latter produces a plant similar to that from which it came. The process is considered a sexual one, though the cells which unite cannot be distinguished as male and female.

In science:

There is a bijection between the W −orbits of C0 (Φ) and the vertices of Γ, having the property that for every point t in the orbit Op corresponding to the vertex p, Φ(t) is W −conjugate to Φp and W (t) is W −conjugate to Wp .

We recall that W ≃ N/T and the action of W on T is induced by the conjugation action of N ; it is also well known that two points of T are G−conjugate if and only if they are W −conjugate.

Thus z t′ and t are G−conjugate elements of T , and hence they are W −conjugate, proving the claim.
Combinatorics and topology of toric arrangements defined by root systems
Following Dyson [Dys62] we assume that the special element T represents an inversion symmetry such as time reversal or charge conjugation. T must then be a (pro jective) involution, i.e., T 2 = z × IdV with 0 6= z ∈ C , so that conjugation by T 2 is the identity operation.
