of, relating to, or caused by a projection

3

Of or related to projective geometry:

Hence the non-Euclidean angle is measured by one-half the logarithm of the cross-ratio of four rays. Although the Euclidean point of view has been adopted for simplicity, the final result, depending as it does only on the cross-ratio, is projective; it is therefore independent of the particular assumptions that the rays α and β are perpendicular and that the initial line bisects the angle between them.

In a technical sense, general (but not necessarily so general as to be free); involving such objects:

noun

1

An assessment test that presents subjects with some sort of stimulus to which they react by projecting or imagining details.

The projectives suggested considerable difficulty with women and a conflict between sexual preoccupation and hostility.

For example, using projectives as a psychometric technique allows one to compare a person's score with those from a normative group, or with those from some relevant clinic group, or with some other clinically important criterion (e.g., response to treatment).

2

A projective member of a category.

By 2.2 we see that this is a full, contravariant imbedding, and by 2.3 the image of A in (A, G) is a generating set of small projectives.

In particular our assumptions hold if B is an abelian category with enough projectives.

3

A statement about a conditional or potential state of affairs, as opposed to one about a situation that actually exists or existed.

There was no basis for expecting differences in the frequency of projectives or turnabouts as a function of partner.

The volitive moods (also called volitives, volitional forms, modals, or projectives) are the imperative, jussive, and cohortative.
