Variational Integrators for the Gravitational N-Body Problem [PDF]

open access: yes, 2006
This paper describes a fourth-order integration algorithm for the gravitational N-body problem based on discrete Lagrangian mechanics. When used with shared timesteps, the algorithm is momentum conserving and symplectic.

A Dynamical Survey of the Trans-Neptunian Region. I. Mean-motion Resonances with Neptune

open access: yesThe Astrophysical Journal Supplement Series, 2023
In this paper, we present a large-scale dynamical survey of the trans-Neptunian region, with particular attention to mean-motion resonances (MMRs). We study a set of 4121 trans-Neptunian objects (TNOs), a sample far larger than in previous works.

An elegant solution of the n-body Toda problem [PDF]

open access: yes, 1995
The solution of the classical open-chain n-body Toda problem is derived from an ansatz and is found to have a highly symmetric form. The proof requires an unusual identity involving Vandermonde determinants.

On the regular-geometric-figure solution to the N-body problem [PDF]

open access: yes, 2001
The regular-geometric-figure solution to the $N$-body problem is presented in a very simple way. The Newtonian formalism is used without resorting to a more involved rotating coordinate system.

Explicit Solution to the N-Body Calogero Problem

open access: yes, 1992
We solve the N-body Calogero problem, \ie N particles in 1 dimension subject to a two-body interaction of the form $\half \sum_{i,j}[ (x_i - x_j)^2 + g/ {(x_i - x_j)^2}]$, by constructing annihilation and creation operators of the form $ a_i^\mp =\frac 1

Infinite-body optimal transport with Coulomb Cost [PDF]

open access: yes, 2013
We introduce and analyze symmetric infinite-body optimal transport (OT) problems with cost function of pair potential form. We show that for a natural class of such costs, the optimizer is given by the independent product measure all of whose factors are

New Classes of Spatial Central Configurations for N + N + 2-Body Problem

open access: yesAbstract and Applied Analysis, 2012
Under arbitrary masses, in this paper, we discuss the existence of new families of spatial central configurations for the N + N + 2-body problem, 𝑁≥2.

Analytic Harmonic Approach to the N-body problem

open access: yes, 2011
We consider an analytic way to make the interacting N-body problem tractable by using harmonic oscillators in place of the relevant two-body interactions.
