Four vector invariant
WebMar 1, 2015 · In this parameterization, the four velocity takes the form u μ = ( γ, γ v x, γ v y, γ v z) where γ = ( 1 − v 2) − 1 / 2. Then it's easy to explicitly check that u μ u μ = − γ 2 + γ 2 v → ⋅ v → = − γ 2 ( 1 − v 2) = − 1 Note that this assumes v → < 1, since otherwise γ is not a finite real number. WebInvariant theory is a branch of abstract algebra dealing with actions of groups on algebraic varieties, such as vector spaces, from the point of view of their effect on functions. …
