Connection - calculation of connection 1-forms

Connection[id]
allows one to calculate or define connection 1-forms
  • id - variable - connection identifier.
  • If a metric is defined, then the connection is calculated with respect to the metric, otherwise just the connection identifier is declared as a connection. If the identifier is a table then the table is declared as a connection (see example 3). To get the result of the calculation use iota operator.
