方程(16)是对李代数元素的作用,对应于群。共伴作用是该作用的对偶,并基于一个标量的不变性。我们称这个标量为S,从该标量我们可以计算群在其动量上的共伴作用。我们从标量计算群g3的共伴作用:
(17) c dJ + S
群g3在其动量上的共伴作用为:
(18) (4529)
群g3的动量为:
(19) J = { c , 群G的动量 }
群的扩展在动量中增加了一个分量c,它服从(20)。特别是,如果,即:
(20) (4531)
它的共伴作用为:
(21) c' = l m c
(22) (4532)
(23) (4533)
方程(22) + (23)对应于当L是洛伦兹群的中性部分时的庞加莱群的共伴作用。
我们知道我们可以将庞加莱群gp的动量Jp放入一个反对称矩阵中:
(24) (4534)
它对这个动量的作用为:
(25) (4535)
然后我们可以写成:
(26) **J **= { c , Jp }
以及:
(27) (4536) c' = l m c
庞加莱群的维度是十。这个扩展群的维度是十一,因为添加了新的变量f。(l = ±1)和(m = ±1)并不代表群的新维度。
这种方法可以无限扩展。考虑以下矩阵:
(28) (4537)
庞加莱群有十个维度。集合(f1,f2,f3,f4,f5,f5)增加了六个额外的维度。标量(l1,l2,l3,l4,l5,l5)是固定的,并不代表新的维度。
群在其动量上的共伴作用
(29) J = { c1 , c2 , c3 , c4 , c5 , c6 , Jp }
为:
(30) (4538) c'i = li m ci,其中i = {1 , 2 , 3 , 4 , 5 , 6 }

f4505 Geometrization of matter and antimatter through coadjoint action of a group on its momentum space. 4 : The Twin group. Geometrical description of Dirac's antimatter. Geometrical interpretations of antimatter after Feynmann and so-called CPT-theorem. (p5)
The equation (16) is the action on the Lie algebra element , corresponding to the group .The coadjoint action is the dual of this action and is based on the invariance of a scalar. Call S this scalar from which one computes the coadjoint action of the group on its momentum. We compute the coadjoint action of the group g3 from the scalar :
(17) c dJ + S
Then the coadjoint action of the group g3 on its momentum is :
(18) (4529)
The moment of the group g3 is :
(19) J = { c , momentum of the group G }
The extension of the group adds a component c to the moment, which obeys (20). In particular, if , i.e :
(20) (4531)
its coadjoint action is :
(21) c' = l m c
(22) (4532)
(23) (4533)
The equations (22) + (23) identifies to the coadjoint action of the Poincaré group when L is the neutral component of the Lorentz group.
We know that we can put the momentum Jp of the Poincaré group gp into an antisymmetric matrix :
(24) (4534)
The its action on this momentum is :
(25) (4535)
Then we can write :
(26) **J **= { c , Jp }
and :
(27) (4536) c' = l m c
The Dimension of the Poincaré group is ten. The dimension of this extended group is eleven, due to adding the new variable f . ( l = ± 1 ) and ( m = ± 1 ) are not new dimensions of the group.
This method can be extended as many times as one wants. Consider the following matrix :
(28) (4537)
The Poincaré group depends owns ten dimensions. The set ( f1 ,f2 , f3 , f4 , f5 , f5 )
adds si more dimensions. The scalar ( l1 ,l2 , l3 , l4 , l5 , l5 ) are fixed and do not correspond to new dimensions.
The coadjoint action of the group on its momentum
(29) J = { c1 , c2 , c3 , c4 , c5 , c6 , Jp }
is :
(30) (4538) c'i = li m ci with i = { 1 , 2 , 3 , 4 , 5 , 6 }
