IBPIdentities

IBPIdentities[fields,devNo]

returns a list with all the integration-by-part identities used by GreensSimplify for the class of operators consisting of the exact matter fields (including Bars) and the specified number of derivatives. Field strength tensors count as 2 derivatives.

Details and Options

  • The following options can be given:
  • ReductionIdentitiesdDimensionalOption for GreensSimplify to decide whether or not to use the subset of identities valid only in 4 dimensions (fierz, gamma reduction and Levi-Civita relations) in the simplification.                  The value can be dDimensional (4D identies are not included), FourDimensional (4D identities are included), Evanescent (4D identities are included with the corresponding evanescent operators) or EvanescenceFree (4D identities are included and evanescent contributions are evaluated).
