Discussion Overview

The discussion revolves around resources and exercises related to the 3-body problem, specifically focusing on the challenges of finding suitable materials for study and preparation. Participants express their experiences and seek guidance on both general and specific aspects of the problem, including the Restricted Circular Three-Body Problem and related concepts.

Discussion Character

  • Exploratory
  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant expresses difficulty in finding exercises or resolved examples for the 3-body problem, noting that resources are more readily available for the 2-body problem.
  • Another participant highlights the complexity of the 3-body problem due to the presence of three interaction terms, suggesting that this contributes to the scarcity of exercises.
  • A participant specifically mentions interest in the Restricted Circular Three-Body Problem, seeking exercises related to the Jacobi constant, Zero Velocity Curves, and Lagrange Points, which are relevant to their course on Solar System Dynamics.
  • One participant suggests determining stationary points and assessing their stability under small perturbations as a potential area of focus.
  • A different participant shares their experience with proving the existence of solutions to the N-Body problem, discussing the challenges and complexities involved in their calculations.
  • Another participant references a historical resource, 'A treatise on the analytical dynamics of particles and rigid bodies: with an introduction to the problem of three bodies' by E.T. Whittaker, as a potential reference.
  • Links to online resources related to the 3-body problem are shared by a participant, which may assist others in their studies.

Areas of Agreement / Disagreement

Participants generally agree on the challenges of finding resources for the 3-body problem, but multiple competing views exist regarding the specific aspects of the problem that are of interest and the types of resources that may be helpful.

Contextual Notes

Some participants mention specific areas of focus, such as the Restricted Circular Three-Body Problem and stability analysis, which may limit the applicability of shared resources to broader contexts. Additionally, the discussion reflects varying levels of familiarity with the mathematical complexities involved in the problem.

Hello,
I am currently studying the 3-body problem and I am struggling to find some examples of exercises or resolved examples.

Can anyone point me to a good book or resource I can download?

I found a few good ones for the two-body problem when I was studying it and they were very useful for me to consolidate the fundamentals.

Thank you very much.

Three body problems are difficult because you have three interaction terms..they're comminly not taught and hence few exercises can be found
 
I am more interested in the Restricted Circular Three-Body Problem case. Which is a little easier. I am looking for exercises involving the Jacobi constant, Zero Velocity Curves, Lagrange Points, etc. This is a major part of my course on Solar System Dynamics.

Any help will be much welcome.
 
determine where the stationary points are and find which ones are stable under small perturbations
 
I have done that.
I am interested in general resolved questions to help me prepare for the exam.
 
The closest I've ever come to making actual calculations involving Newtonian Gravity with more than two bodies was proving that there always existed a solution to the N-Body problem. That took three days and a lot of caffeine and I don't think I could do it twice. Something about it being decomposable into an infinite dimensional linear partial differential equation (it had an infinite number of variables). Unfortunately I've lost the proof. I looked at the proof that already existed afterwards and it was similar, but not the same. Somehow, this infinite dimensional linear partial differential equation had solutions, at least in theory, although I never found a general solution and I don't think the differential equation I came up with would be very useful because it didn't show singularities and likely wouldn't unless you inputted an infinite number of coefficients (or perhaps the right coefficient), due to the nature of singularities in linear differential equations.

My recollection is that there has been quite a lot of work done on the three-body problem, particularly by a French mathematician whose name is escaping me now (I really should know his name, because he's quite well known). In general, you'll find more work done by mathematicians than by physicists, excepting, of course, mathematical physicists.

Good luck!
 
An old one is 'A treatise on the analytical dynamics of particles and rigid bodies:
with an introduction to the problem of three bodies' by E.T. Whittaker.
