Lorentz boost , boost (Abkürzung) *

Consider a Lorentz boost in a fixed direction z.

The contextual difference is profound enough to then separate Lorentz boost from squeeze mapping.

The second method proceeds by diagonalizing the Lorentz boost.

Poincaré performed a Lorentz boost (to order v/c) to the frame of the moving source.

Any such velocity can be viewed as a zero velocity under a squeeze mapping called a Lorentz boost.

With the further development of special relativity the action of a hyperbolic versor came to be called a Lorentz boost.

Since the early twentieth century, the split-complex multiplication has commonly been seen as a Lorentz boost of a spacetime plane.

Among the simplest Lorentz transformations is a Lorentz boost.

One way to describe a Lorentz boost is as a hyperbolic rotation which preserves the differential angle between rapidities.

One can define geometrical quantities that measure the Lorentz boost and area increase on going round these closed null geodesics.

It may include a rotation of space; a rotation-free Lorentz transformation is called a Lorentz boost.

Basically, it states that spinning objects precess when they accelerate in special relativity because Lorentz boosts do not commute with each other.

Since the direction r in space is arbitrary, this hyperbolic quaternion multiplication can express any Lorentz boost using the parameter a called rapidity.

The transverse mass is a useful quantity to define for use in particle physics as it is invariant under Lorentz boost along the z direction.

This squashing comes from the non-linearity of the Lorentz boost and is an endemic feature of bicrossproduct quantum groups known since their introduction in 1988.

These transformations are generalization of the Lorentz boost in a fixed space direction (x) in the field of the multidimensional time and multidimensional space.

The formulas for boosts in the standard configuration follow most straightforwardly from taking differentials of the inverse Lorentz boost in standard configuration,.

This length is preserved under any Lorentz boost or rotation in four dimensions, just like the ordinary length of a vector is preserved under rotations.

In general if one multiplies a Lorentz boost on the right by a momentum-dependent rotation, which leaves the rest vector unchanged, the result is a different type of boost.

To see the exponential mapping heuristically, consider the infinitesimal Lorentz boost in the x direction for simplicity (the generalization to any direction follows an almost identical procedure).

Lorentz boosts can be parametrized by rapidity, and a 3d unit vector n pointing in the direction of the boost, which combine into the "rapidity vector"

In Minkowski space-time, in pseudo-Cartesian coordinates with signature an example of Killing horizon is provided by the Lorentz boost (a Killing vector of the space-time)

Accompanying velocity addition is a kinematic effect known as Thomas precession, whereby successive non-collinear Lorentz boosts become equivalent to the composition of a rotation of the coordinate system and a boost.

But a rotation in a plane spanned by a space dimension and a time dimension is a hyperbolic rotation, a transformation between two different reference frames, which is sometimes called a "Lorentz boost".

Since λ has modulus 1, multiplying any split-complex number z by λ preserves the modulus of z and represents a hyperbolic rotation (also called a Lorentz boost or a squeeze mapping).
