The symbol ∇ can be interpreted as a vector differential operator,where the term operator means that ∇ only has a meaning when it acts on some other quantity. Theorem 3.1 Suppose that a vector field F is related to a scalar field Φ by F = ∇Φ and ∇ exists everywhere in some...

• Now if some vector field a is itself derived from a scalar field via a = ∇φ , then ∇ ·a has the form ∇ ·∇φ or, as it is usually 2 2 written, ∇ φ , where ∇ (del squared) is the scalar differential operator 2 ∇ φ is called the Laplacian ofφ . ...
For this weintroduce particular differential operators of arbitrary order attached toGegenbauer polynomials. These differential operators are symmetry breaking forthe pair of Lie groups $(SL(2,\mathbb C), SL(2,\mathbb R))$ that arise fromconformal geometry....
Example 6.79Let be the vector space of all differentiable functions. Consider the subspace W of given by W = span(e3, xe3, x2e3). Since the set B = {e3, xe3, x2e3} is linearly independent (why?), it is a basis for W.(a)Show that the differential operator D maps W into itsel...
The tangent space is then the vector space spanned by the differential operators (∂∂ξi)p: Tp(M)={ci(∂∂ξi)p|[c1,…,cn]∈eRn}, where the differential operator (∂∂ξi)p can be seen geometrically as the tangent vector to the ith coordinate curve (fixing all ξj ...
