WebSep 5, 2024 · Now let's look at the field vector at some point at displacement $\vec r$ from the center of the spherical vector field, and consider rotations of the spherical vector field around the axis through the origin and the chosen point, that is, rotations parallel to $\vec r$. The field vector at that point must be unchanged by any such rotation.

In mathematics, the symmetric algebra S(V) (also denoted Sym(V)) on a vector space V over a field K is a commutative algebra over K that contains V, and is, in some sense, minimal for this property. Here, "minimal" means that S(V) satisfies the following universal property: for every linear map f from V to a commutative algebra A, there is a unique algebra homomorphism g : S(V) → A such that f = g ∘ i, where i is the inclusion map of V in S(V).
