Covariant derivative spherical coordinates
WebOnce again, I'm not a big fan of this notation. To define a covariant derivative, then, we need to put a "connection" on our manifold, which is specified in some coordinate system by a set of coefficients (n 3 = 64 independent components in n = 4 dimensions) which transform according to (3.6). (The name "connection" comes from the fact that it is used … WebCovariant Derivatives Important property of affine connection is in defining covariant derivatives: A μ, ν = ∂ A μ / ∂ x ν On the previous page we defined Now consider a new coordinate system ¯ x ↵ = ¯ x ↵ (x) Because of this term, is not a tensor ¯ A μ, ν We have that ¯ A μ, ν = ∂ ¯ A μ ∂ ¯ x ν = ∂ ∂ ¯ x ν ∂ ...
