Lie's motivation when he created what is now known as Lie groups and Lie algebras; nevertheless, although Lie group and algebra theory flourished and was applied to a number of dift\"erent physical situations -up to the point that a lot, if not most, of current fun- damental elementary particles physics is actually (physical interpretation of) group theory -the application of symmetry methods to dift\"erential equations remained a sleeping beauty for many, many years. The main reason for this lies probably in a fact that is quite clear to any beginner in the field. Namely, the formidable comple: rity ofthe (algebraic, not numerical!) computations involved in Lie method. I think this does not account completely for this oblivion: in other fields of Physics very hard analytical computations have been worked through; anyway, one easily understands that systems of dOlens of coupled PDEs do not seem very attractive, nor a very practical computational tool.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45282395979927,"sku":"9789401044431","price":3672.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9789401044431.webp?v=1769302027","url":"https:\/\/atlanticbooks.com\/products\/nonlinear-symmetries-and-nonlinear-equations-9789401044431","provider":"Atlantic Books","version":"1.0","type":"link"}
