Maxima Function
christof (dis)
A function in the ctensor
(component tensor)
package. It computes the Christoffel symbols of both
kinds. The argument dis determines which results are to be immediately
displayed. The Christoffel symbols of the first and second kinds are
stored in the arrays lcs[i,j,k]
and mcs[i,j,k]
respectively and
defined to be symmetric in the first two indices. If the argument to
christof
is lcs
or mcs
then the unique non-zero values of lcs[i,j,k]
or mcs[i,j,k]
, respectively, will be displayed. If the argument is all
then the unique non-zero values of lcs[i,j,k]
and mcs[i,j,k]
will be
displayed. If the argument is false
then the display of the elements
will not occur. The array elements mcs[i,j,k]
are defined in such a
manner that the final index is contravariant.
