Saari's Homographic Conjecture of the Three-Body Problem
Saari's homographic conjecture, which extends a classical statement proposed
by Donald Saari in 1970, claims that solutions of the Newtonian -body
problem with constant configurational measure are homographic. In other words,
if the mutual distances satisfy a certain relationship, the configuration of
the particle system may change size and position but not shape. We prove this
conjecture for large sets of initial conditions in three-body problems given by
homogeneous potentials, including the Newtonian one. Some of our results are
true for
Three body relative equilibria on
We study relative equilibria ( in short) for three-body problem on
, under the influence of a general potential which only depends
on where are the mutual angles among the
masses. Explicit conditions for masses and to form
relative equilibrium are shown. Using the above conditions, we study the equal
masses case under the cotangent potential. We show the existence of scalene and
isosceles Euler , and isosceles and equilateral Lagrange .Comment: 25 pages, 5 figures. arXiv admin note: substantial text overlap with
