The unitary group

For this Lie group, several implementations are already covered by the defaults in the generic (matrix) multiplication operation. Besides that the following methods are implemented:

Utility functions and constants

LieGroups.CommonUnitarySubGroupType
CommonUnitarySubGroup{𝔽,T}

A constant that allows to refer to several subgroups of $\mathrm{U}(n)$ for implementations where

  • certain subgroups real/complex share a common implementation, e.g. for the same sizes T usually via TypeParameter
  • certain functions are the same for all sizes T as long as the field 𝔽 is the same
