The two conserved vectors, A and B can be combined to form a conserved dyadic tensor W, W = α α A ⊗ ⊗ A + β β B ⊗ ⊗ B , where α and β are arbitrary scaling constants and ⊗ ⊗ represents the tensor product (which is not related to the vector cross product, despite their similar symbol). Written in explicit components, this equation reads W i j = α α A i A j + β β B i B j .
