The term B.(Gradient . B) represents the dot product of the vector field B with the gradient of B. The term B X (Gradient X B) represents the cross product of B with the curl of B. The term Del{i}B{i}B{j} represents the del operator applied to the product of two ...
Namely, a basis of ∇k-potential-quasiaffine functions are already ∇-potential quasiaffine functions for the gradient acting on C∞(RN,RN⊗sym⋯⊗symRN). 4.2 The divergence operators on matrices Consider the divergence operator acting on matrices, i.e. div:C∞(RN,RN×d)⟼C∞(...
