In special relativity, a four-vector (or 4-vector, sometimes Lorentz vector) [1] is an element of a four-dimensional vector space object with four components, which transform under Lorentz …

The four-vector is introduced that unifies space-time coordinates x, y, z and t into a single entity whose components get mixed up under Lorentz transformations.

A four-vector is a mathematical object in the framework of special relativity that combines space and time into a single entity, allowing for a unified description of events in spacetime.

Mar 5, 2022 · But a four-vector that vanishes in one frame also vanishes in every other frame. That means we’re talking about a particle that can’t undergo scattering, emission, or …

Dec 22, 2025 · In the Minkowski space of special relativity, a four-vector is a four-element vector that transforms under a Lorentz transformation like the position four-vector.

May 28, 2024 · Learn about four-vectors in physics: their key concepts, basics, unique components, and significant applications in relativity and spacetime transformations. In the …

In the literature of relativity, space-time coordinates and the energy/momentum of a particle are often expressed in four-vector form. They are defined so that the length of a four-vector is …

Jun 13, 2025 · Four-Vectors are mathematical objects used to describe physical quantities in four-dimensional spacetime. They are defined as a set of four components that transform under …

Dec 15, 2017 · Extending this to spacetime, a four-vector is a quantity with magnitude and direction in spacetime. Implicit in this definition is the notion that the vector's magnitude is a …
