WebJul 22, 2024 · Taking the inverse of both sides: η = Λ − 1 η ( Λ − 1) T However, what actually is Λ − 1 is semantics since this equation holds for all Λ anyway, so we could just as well write η = Λ η Λ T. One final way to show that η ′ = η is through the transformation of η μ ν instead of η μ ν: η μ ν ′ = Λ α μ Λ β ν η α β = ( Λ T) μ α η α β Λ β ν WebThe first step is to define the inverse of the metric. Using matrix notation, the metric is its own inverse: η η = 1. But we want to use index notation, so we define another object, call it ζ, with components ζ μ ν = η μ ν. With this, you can check that η η = 1 can be writen as η μ ν ζ ν ρ = δ ρ μ, where δ is the Kronecker symbol. dhr.alabama.gov child care
