Curvature form
From Encyclopedia of Mathematics
A 
-form 
on a principal fibre bundle 
with structure Lie group 
, taking values in the Lie algebra 
of the group 
and defined by the connection form 
on 
by the formula
 |
The curvature form is a measure of the deviation of the given connection from the locally flat connection characterized by the condition 
. It satisfies the Bianchi identity
 |
and defines the holonomy algebra (see Holonomy group).
Comments
The equation 
is called the structure equation.
