Proper Velocity Space Model and Proper Velocity Addition
A proper velocity space model of hyperbolic geometry is given by proper velocities with vector addition given by the proper velocity addition formula:
where is the beta factor given by .
This formula provides a model that uses a whole space compared to other models of hyperbolic geometry which use discs or half-planes.
A proper velocity gyrovector space is a real inner product space V, with the proper velocity gyrogroup addition and with scalar multiplication defined by r v = s sinh(r sinh−1(|v|/s))v/|v| where r is any real number, v ∈ V, v ≠ 0 and r 0 = 0 with the notation v r = r v.

Famous quotes containing the words proper, space, model and/or addition:
“Exaggeration is in the course of things. Nature sends no creature, no man into the world, without adding a small excess of his proper quality. Given the planet, it is still necessary to add the impulse; so, to every creature nature added a little violence of direction in its proper path, a shove to put it on its way; in every instance, a slight generosity, a drop too much.”
—Ralph Waldo Emerson (18031882)
“... the space left to freedom is very small. ... ends are inherent in human nature and the same for all.”
—Hannah Arendt (19061975)
“The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery....Childs play is the infantile form of the human ability to deal with experience by creating model situations and to master reality by experiment and planning.”
—Erik H. Erikson (20th century)
“As easy mayst thou fall
A drop of water in the breaking gulf,
And take unmingled thence that drop again,
Without addition or diminishing,
As take from me thyself and not me too.”
—William Shakespeare (15641616)
