Periodic Solutions for Circular Restricted -Body Problems [PDF]
For circular restricted -body problems, we study the motion of a sufficiently small mass point (called the zero mass point) in the plane of equal masses located at the vertices of a regular polygon. By using variational minimizing methods, for some , we prove the existence of the noncollision periodic solution for the zero mass point with some fixed ...

Minimal velocity surface in the restricted circular Three-Body-Problem
In the framework of the restricted circular Three-Body-Problem, the concept of the minimum velocity surface S is introduced, which is a modification of the zero-velocity surface (Hill surface). The existence of Hill surface requires occurrence of the Jacobi integral. The minimum velocity surface, other than the Jacobi integral, requires conservation of

Four-body co-circular central configurations [PDF]
We classify the set of central configurations lying on a common circle in the Newtonian four-body problem. Using mutual distances as coordinates, we show that the set of four-body co-circular central configurations with positive masses is a two-dimensional surface, a graph over two of the exterior side-lengths.

Noncollision Periodic Solutions for Circular Restricted Planar Newtonian Four-Body Problems
We study a class of circular restricted planar Newtonian four-body problems in which three masses are positioned at the vertices of a Lagrange equilateral triangle configuration, each mass revolving around the center of mass in circular orbits.

Orbits in the two-body problem in terms of symmetries [PDF]
For the two-body problem computed 12-parameter group symmetry transformations which translate the obvious solution - uniform motion of bodies in circular orbits with a common fixed center - a motion with arbitrary initial data.

Short-range guiding can result in the formation of circular aggregates in myxobacteria populations. [PDF]
Myxobacteria are social bacteria that upon starvation form multicellular fruiting bodies whose shape in different species can range from simple mounds to elaborate tree-like structures.

Wave forces on fixed vertical axisymmetric bodies
In this paper, wave forces on fixed vertical axisymmetric bodies are considered by the hybrid boundary element method. A program package on Fortran IV on PC has been developed and applied for the cases of a vertical circular (large and small diameter ...
