pseudovector

[¦sü·dō′vek·tər] (physics) A quantity which transforms as a vector under space rotations but which transforms as a vector, together with a change in sign, under a space inversion. Also known as axial vector. A quantity which transforms as a four-vector under Lorentz transformations, but with an additional sign change under space reflection or time reflection or both.

Pseudovector

Pseudovector

 

a vector determined to within an arbitrary numerical factor (vector direction). For example, the homogeneous coordinates x1, x2, x3, x4 of a point in three-dimensional space with a fixed coordinate system can be considered as the components (coordinates) of a four-dimensional pseudovector.
