Contorsion Routine for Mixed Vielbeins
This routine is devised to calculate the contorsion tensor in the following very common situation where the vielbein of a space in dimension
n=1+r
is given in the following form: e1=A(μ)dμ
ei =fi (μ) σ i
where |
fi (μ) are functions of the |
coordinate μ and σ i are vielbeins of an r- |
|||
dimensional space for which the contorsion is already known: |
|||||
dσ i = - tjki σ j σ k |
|

So that we find: |

Calculation of the Contorsion for General Manifolds
This routine is devised to calculate the contorsion for general manifolds. The inputs are
1)the dimension n
2)the set of coordinates a n vector = coordi
3)the set of differentials, a nnn vector = diffe
4)the set of vielbein 1-forms a nnn vector = fform
TO START this programme you type contorgen and then you follow instructions
Calculation for Cartan Maurer Equations and Vielbein Differentials (Euclidian Signature)
This package is devised to calculate the exterior differential of a set of 1-forms, for instance vielbeins or Cartan Maurer 1-forms.
This part is initialized by typing extdiff then you follow the computer instructions.
SO(3), SO(4) t’ Hooft Matrices and Euler Angles
This programme is devised to calculate the differential 1 forms on the 3 sphere in terms of the Euler angles, introducing the self-dual and antiself-dual generators of the SO(4) group, namely the ’t Hooft matrices. This calculation relies on the routine spheres belonging to another section of this notebook.
