PartialDev

PartialDev[Index[μ, Lorentz]]

is used as a wrapper around Lorentz indices in the derivative list of Field/FieldStrength objects to mark them as partial (rather than covariant) derivatives.

Details and Options

  • PartialDev is not meant to be called directly as a user, it is merely part of the internal notation. The user can use PD to take a partial derivative of a Field or expression.
