The contra-variant transform seems to be defined by the differential transform from calculus.(adsbygoogle = window.adsbygoogle || []).push({});

dx[itex]^{\mu}[/itex]=x[itex]^{\mu}_{,\nu}[/itex]dx[itex]^{\nu}[/itex]

A[itex]^{\mu}[/itex]=x[itex]^{\mu}_{,\nu}[/itex]A[itex]^{\nu}[/itex]

I am puzzled by this, as the vector / tensor usually has finite components. They span a considerable region of space. So where are the partials to be taken, i.e., at what point in space or space-time?
