This fact could give rise to problems: you may have different configuration spaces at different times (think of a point moving along a curve which changes it shape in time). Assuming to work with a jet bundle, actually the fibers must be diffeomorphic but not isometric, this is a mild condition which remains when using the fiber bundle structure... | |
