WebAnalytically, it means the vector field can be expressed as the gradient of a scalar function. To find this function, parameterize a curve from the origin to an arbitrary point {x, y}: ... The double curl of a scalar field is the Laplacian of that scalar. In two dimensions: WebMar 12, 2024 · Its obvious that if the curl of some vector field is 0, there has to be scalar potential for that vector space. ∇ × G = 0 ⇒ ∃ ∇ f = G. This clear if you apply stokes theorem here: ∫ S ( ∇ × G) ⋅ d A = ∮ C ( G) ⋅ d l = 0. And this is only possible when G has scalar potential. Hence proved.
