Web1. The Helmholtz-Hodge decomposition. A special case of the Helmholtz-Hodge theorem states that any vector field that is tangent to the sphere can be uniquely decomposed into a sum of a surface divergence-free component and a surface curl-free component. In this Example, we show how this decomposition can be computed by Spherefun and introduce ...
