Hi! This group is more for discussion of educational and teaching ideas. Implementing new capability in Sage for solving differential equations would get more people on the sage-devel Google group. Note that a lot of our functionality is used from Maxima; perhaps it has some of this implemented already? Good luck! > > > I recently bought the book that I studied in my PhD years. It is > "*Differential > Equations: their solution using symmetries*" by Hans Stephani. > https://www.amazon.com/Differential-Equations-Their-Solution-Symmetries/dp/0521355311/ref=sr_1_1?dchild=1&keywords=hans+stephani+differential+equation&qid=1591870417&sr=8-1 > > In the book, methods to solve nonlinear ODE's or PDE's are given if the > differential equation has an underlying Lie group symmetry.
