RelativisticN-body problem in a separable two-body basis [PDF]

open access: green, 2001
We use Dirac's constraint dynamics to obtain a Hamiltonian formulation of the relativistic N-body problem in a separable two-body basis in which the particles interact pair-wise through scalar and vector interactions.

Hidden algebra of the N-body Calogero problem [PDF]

open access: green, 1994
A certain generalization of the algebra $gl(N,{\bf R})$ of first-order differential operators acting on a space of inhomogeneous polynomials in ${\bf R}^{N-1}$ is constructed. The generators of this (non)Lie algebra depend on permutation operators. It is

Integrability and Non Integrability of Some n Body Problems [PDF]

open access: green, 2016
We prove the non integrability of the colinear $3$ and $4$ body problem, for any masses positive masses. To deal with resistant cases, we present strong integrability criterions for $3$ dimensional homogeneous potentials of degree $-1$, and prove that ...

Accelerating Polyhedral Discrete Element Method with CUDA

open access: yesThe Astronomical Journal, 2023
This paper presents an efficient CUDA-based implementation of a nonspherical discrete element method where irregular particles are described by using polyhedrons. Two strategies are employed to exploit the parallelism of the numerical method.

Regular Polygon Central Configuration of the Restricted 1 + N-Body Problem

open access: yesUniverse, 2023
We consider the central configurations of the 1+N-body problem, where N bodies are infinitesimal and the remaining one body is dominant. For regular polygon central configurations, we prove that the masses of all the infinitesimal bodies are equal when N

Planetesimal Accretion at Short Orbital Periods

open access: yesThe Astrophysical Journal, 2023
Formation models in which terrestrial bodies grow via the pairwise accretion of planetesimals have been reasonably successful at reproducing the general properties of the Solar System, including small-body populations. However, planetesimal accretion has

Periodic Solutions for N-Body-Type Problems [PDF]

open access: yesChinese Annals of Mathematics, Series B, 2020
We consider non-autonomous $N$-body-type problems with strong force type potentials at the origin and sub-quadratic growth at infinity, and using Ljusternik-Schnirelmann theory, we prove the existence of unbounded sequences of critical values for the Lagrangian action corresponding to non-collision periodic solutions.
