Can connections on a principal bundle have torsion?

356 Views Asked by At

In Riemannian geometry, one defines torsion and curvature for the affine/metric connection. Is it possible to define a torsion form for a connection which is defined on a principle G-bundle?

Any references would really be appreciable. Thanks!

The curvature of a connection defined on a principal bundle is the covariant derivative of the connection form.
