WebThe gradient of a function has covariant components because it naturally is a map T M → R. It takes a vector and gives you the directional derivative of the function in that direction. So it is an element of T ∗ M (the dual space to T M ), whose basis has a transformation behaviour (contravariant) opposite to that of the basis of T M (covariant). WebMay 20, 2003 · Covariant The partial derivative above may have you thinking of a gradient. The gradient is the prototype for a covariant vector which is defined as ∂ϕ0 ∂x0 i = X j ∂ϕ ∂xj ∂xj ∂x0 i Covariant vectors are actually a linear form an not a vector. The linear form is a mapping of vectors into scalars which is additive and homoge-
