SymCovDQ

SymCovDQ[cd]
gives True if cd has been defined as a symmetrizable covariant derivative, and False otherwise.
SymCovDQ
is also an option for DefCovD specifying whether the derivative to be defined is symmetrizable or not.
  • The default value for the option SymCovDQ of DefCovD is False.

Basic Examples   (1)
A symmetrizable covariant derivative can be defined as follows:
Note that the option SymCovDQ could also have been given to DefMetric.
CD is now registered as a symmetrizable covariant derivative:
This means that we can now use multipe incides to indicate symmetrize derivative:
