WebMar 14, 2024 · 11.10: Closed-orbit Stability. Bertrand’s theorem states that the linear oscillator and the inverse-square law are the only two-body, central forces for which all bound orbits are single-valued, and stable closed orbits. The stability of closed orbits can be illustrated by studying their response to perturbations. In classical mechanics, Bertrand's theorem states that among central-force potentials with bound orbits, there are only two types of central-force (radial) scalar potentials with the property that all bound orbits are also closed orbits. The first such potential is an inverse-square central force such as the gravitational or … See more All attractive central forces can produce circular orbits, which are naturally closed orbits. The only requirement is that the central force exactly equals the centripetal force, which determines the required angular velocity for … See more For an inverse-square force law such as the gravitational or electrostatic potential, the potential can be written $${\displaystyle V(\mathbf {r} )={\frac {-k}{r}}=-ku.}$$ The orbit u(θ) can be derived from the general equation See more • Goldstein, H.

WebThe mathematical theory of stability of motion, founded by A. M. Lyapunov, considerably anticipated the time for its implementation in science and technology. Moreover Lyapunov did not himself make application in this field, his own interest being in the stability of rotating fluid masses with astronomical application. WebApr 7, 2024 · Definition 1 The orbit of an element x ∈ X is defined as: O r b ( x) := { y ∈ X: ∃ g ∈ G: y = g ∗ x } where ∗ denotes the group action . That is, O r b ( x) = G ∗ x . Thus the orbit of an element is all its possible destinations under the group action . Definition 2 Let R be the relation on X defined as: ∀ x, y ∈ X: x R y ∃ g ∈ G: y = g ∗ x
