Regular element of a Lie algebra "G", the elements "t" of "T" that are regular in "G" determine the regular elements of "G", which make up the union of the conjugacy classes in "G" of regular elements in "T". The regular elements "t" are themselves explicitly given as the complement of a set in "T", determined by the adjoint action of "G", and making up a union of subtori. Regular element of a Lie algebra In mathematics, a regular element of a Lie algebra or Lie group is an element whose centralizer has dimension as small as possible.
