FV

Description

FV[p, μ] is the four-dimensional vector (p^μ).

See also:  FCE, FCI, FVD, FourVector, Pair.

Examples

FV[p, μ]

FV[p - q, μ]

FV[p, μ] // StandardForm

FCI[FV[p, μ]] // StandardForm

There is no special function to expand momenta in FV; ExpandScalarProduct does the job.

ExpandScalarProduct[FV[p - q, μ]]

StandardForm[%]
