TL;DR: In this paper, a generalization of the central configuration approach is presented, which leads to large continuous families of approximate solutions for uniform motion of equidistributed masses on closed space curves, in the limit when the number of particles tends to infinity.
Abstract: The determination of the exact trajectories of mutually interacting masses (the n-body problem1,2) is apparently intractable for n ⩾ 3, when the generic solutions become chaotic. A few special solutions are known, which require the masses to be in certain initial positions; these are known as ‘central configurations’ (refs 1,2,3,4,5,6) (an example is the equilateral triangle formed by the Sun, Jupiter and Trojan asteroids). The configurations are usually found by symmetry arguments. Here I report a generalization of the central-configuration approach which leads to large continuous families of approximate solutions. I consider the uniform motion of equidistributed masses on closed space curves, in the limit when the number of particles tends to infinity. In this situation, the gravitational force on each particle is proportional to the local curvature, and may be calculated using an integral closely related to the Biot–Savart integral. Approximate solutions are possible for certain (constant) values of the particle speed, determined by equating this integral to the mass times the centrifugal acceleration. Most smooth, closed space curves contain such approximate solutions, because only the local curvature is involved. Moreover, the theory also holds for sets of closed curves, allowing approximate solutions for knotted and linked configurations.

TL;DR: Stochastic processes are proposed whose master equations coincide with classical wave, telegraph, and Klein-Gordon equations, and a new ingredient is that transitions into a given velocity state depend on spatial derivatives of other states populations, rather than on populations themselves.
Abstract: Stochastic processes are proposed whose master equations coincide with classical wave, telegraph, and Klein-Gordon equations. Similar to predecessors based on the Goldstein-Kac telegraph process, the model describes the motion of particles with constant speed and transitions between discreet allowed velocity directions. A new ingredient is that transitions into a given velocity state depend on spatial derivatives of other states populations, rather than on populations themselves. This feature requires the sacrifice of the single-particle character of the model, but allows to imitate the Huygens' principle and to recover wave equations in arbitrary dimensions.
