The Restricted 3-Body Problem: Plane Periodic Orbits
... orbit 1. As a → ∞ , the family continues with such arcs but belongs to parabolic and hyperbolic sideral orbits of the two - body problem . As a → 1 , we obtain orbit 2 represented in Fig . IV.12 by the point a = ē = -1 . Moving on ...
Nilpotent Orbits In Semisimple Lie Algebra
... Orbit Whereas the principal orbit is the largest orbit in N , we can look at the other end of the spectrum and establish the existence of small nilpotent orbits . The trivial orbit { 0 } is the unique nilpotent orbit of minimal ...
