I am interested in learning the theory of Jet bundles, and am aware of the standard reference "The geometry of jet bundles" by D. J. Saunders. However this appears to be a detailed book, suitable for those who wish to specialise in this area. Can somebody recommend a relatively more introductory book (for a reader who knows the necessary differential geometric pre-requisites for learning this subject, but has never encountered Jet bundles) ? Thanks so much !



What would be a good introductory reference for learning jet-bundle theory?
Two articles by A.M. Vinogradov provide a gentle introduction:


"Local symmetries and conservation laws", Acta Applicandae Mathematica volume 2, pages 21–78(1984)


"An informal introduction to the geometry of jet spaces", available [here](https://diffiety.mccme.ru/djvu/informal.djvu).
