Math Forum :: View topic – Can anybody explain what is Lie Integral?

Can anybody explain in a simple manner what is Lie Integral? Can you explain by way of a concrete example how to evaluate such kind of integrals? For example, do we need to perform any transformation or parametrization in order to evalute the integral? If so, what kind of transformation or parametrization? Is there any geometrical or physical significance for such kind of integrals? Many thanks._________________
