WebJan 18, 2015 · The curl of a 1-form A is the 1-form ⋆ dA. The divergence of a 1-form A is the function ⋆ d ⋆ A. The Laplacian of a function or 1-form ω is − Δω, where Δ = dd † + d † d. The operator Δ is often called the Laplace-Beltrami operator. WebFor example, the rotation of the earth in space would be described using a vector pointing from the center of the earth to its north pole, whose length is equal to the angular speed of the earth's rotation (which happens to be 0.0000729 0.0000729 0. 0 0 0 0 7 2 9 0, point, 0000729 radians/second).
