Dear Friends
Not doubts about what is to be meant for "conservative vector field" as far as time independent fields are concerned.
But what about non stationary fields? I thought it was a meaningless concept when field is changing in time: the line integral seems to be not well defined. All in all, why should I add up together values measured in different moments?
Nevertheless I suspect that in lagrangian and hamiltonian formalism someone consider "conservative" a non stationary field if a time varying potential function exists such as, in each instant, (at "frozen time", as Italians call it), the field is its gradient.
What do you think about that? Am I wrong?
Warmest regards.
