Each arrow is labeled with the result of an identity, specifically, the result of applying the operator at the arrow's tail to the operator at its head. The blue circle in the middle means curl of curl exists, whereas the other two red circles (dashed) mean that DD and GG do not exist.

WebDec 31, 2024 · The reason you are taking the curl of curl is because then the left hand side reduces to an identity involving just the Laplacian (as ∇ ⋅ E = 0 ). On the right hand side you have ∇ × B which is just μ 0 ε 0 ∂ E / ∂ t.
