(As the curl is a vector, it is very different from the divergence, which is a scalar.) We can draw the vector corresponding to curl F as follows.

Curl of curl of vector index notation

In vector calculus, the curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space. The curl at a point in the field is represented by a vector whose length and direction denote the magnitude and axis of the maximum circulation. The curl of a field is formally defined as the circulation density at each point of the field. Web= 1 we are able to get to the dot product of two vector quantities. Also we know that in index notation: ... From the deﬁnition of curl in index notation we know: ... For the index notation, starting from the left hand side of equation 29:

Web(The curl of a vector field doesn't literally look like the "circulations", this is a heuristic depiction.) By the Kelvin–Stokes theorem we can rewrite the line integrals of the fields around the closed boundary curve ∂Σ to an integral of the "circulation of the fields" (i.e. their curls ) over a surface it bounds, i.e.

WebI usually just grind through these types of things with the Einstein notation. The notational rule is that a repeated index is summed over the directions of the space.
