Generalized Symmetries,kind of contact transformations are related to point transformations in case of first-order partial differential equations. However, it turns out that much wider classes of transformations leave differential equations invariant, including those considered by Lie.

Introduction,amics. Thus, invariance principles provide a structure and coherence to the laws of nature, just as the laws of nature provide a structure and coherence to the set of events. In fact, it is hard to imagine that progress could have been made in deducing the laws of nature without the existence of cer
