The role of metric in the Wave Equation I was talking about an abstract wave equations, not Maxwell equations. However, this remark is very interesting. I have to to think about it. Do you mean that physically meaningful scalar fields sometimes lose their invariant properties in anisotropic medium, and one is then forced to deal with vector fields? |

The role of metric in the Wave Equation Indices in tensor components are deleted; the formulation was intended to be as coordinate-free as possible. |

The role of metric in the Wave Equation @whoplisp Two equations in the original post are identical. It is an equation for time-dependent scalar field u. What made you think of equation for vector field? |
