Overview and comparison of approaches towards the planar restricted five-body problem with primaries forming an axisymmetric four-body central configuration
The aim of this paper is to present recent results on the restricted five-body problem where the primaries are located at a known central configuration having the x\(x\)-axis as symmetry axis, so that two bodies wi...

Some Qualitative Features of the Isosceles Trapezoidal Four-Body Problem
In this article, we present a novel survey of known qualitative features of the isosceles trapezoidal four-body problem, that has three degrees of freedom, as well as its two subsystems with two degrees of fre...

The Rhomboidal 4-Body Problem Revisited
We consider the planar rhomboidal 4-body problem where the masses are equal by pairs. In this paper we briefly review some recent results related to binary and total collision regularization, central configura...

The trapezoidal collinear four-body problem
This paper consider the trapezoidal collinear four-body problem as a model for binary-binary gravitational interaction in star clusters. It has two degrees of freedom, it also is a sub-problem of the trapezoid...

A model for binary-binary close encounters and collisions from a dynamical point of view
The goal of this paper is to provide a model for binary-binary interactions in star clusters, which is based on simultaneous binary collision of a special case of the one-dimensional 4-body problem where four ...

Symbolic dynamics in the symmetric collinear four-body problem
In this article we prove the existence of a countable number of ejection-collision orbits for the symmetric collinear four body problem with negative energy. These orbits come out from total collision, pass th...

Matrix Multiplication on Digital Signal Processors and Hierarchical Memory Systems
We discuss map** the matrix multiplication algorithm onto a two-level hierarchical memory system which incorporates DMA capabilities between levels, as available on Digital Signal Processors (DSPs). We show ...
