New here. Been working on a research project involving geometric numerical integrators and the n-body problem. Trying to understand the math and physics a bit more. Have been primarily going through the textbook "Geometric Numerical Integration Structure-Preserving Algorithms for Ordinary Differential Equations" by Hairer, Ernst, Lubich, Christian, Wanner, Gerhard. Trying to go through most of the problems in the textbook, as well as understand the theorems and examples provided, so that's what most of my questions will be concerning. I guess maybe I should post under homework help even though this is not really for a class.
