Characterizing Orbital-Reversibility Through Normal Forms
Qualitative Theory of Dynamical Systems, 2021As usual, the local vector fields \(F\) with \(F(0)=0\) are reversible if there is a local diffeomorphism \(\sigma\), satisfying \(\sigma\circ\sigma = Id\), \(\sigma(0)=0\), and turning \(F\) into \(-F\), i.e., \(\sigma_\ast F = -F\). In this paper, \(F\) is called orbitally reversible if \(F\) is reversible by the time representation. Here the authors

Normal Form Invariants Around Spin-Orbit Periodic Orbits
Celestial Mechanics and Dynamical Astronomy, 2000The authors consider an oblate satellite orbiting a central planet with \(T_{\text{rev}}\) the period of revolution. The satellite rotates about an internal spin axis with rotational period \(T_{\text{rot}}\). A spin-orbit resonance occurs when the ratio \(T_{\text{rev}}/T_{\text{rot}}\) is a rational number.

Kinematic Process Plastic Cold Orbital Forming
Applied Mechanics and Materials, 2015In the paper before you, the authors study the kinematics of the orbital deformation process on the base of the trajectory equation of the mobile element of the machine. Also, the authors show that the trajectory is a closed cycle curve with a finite number of lobes.

In the present paper we study the orbits of action of the group GL2(ℂ) on the space of binary forms. The main result of the paper is the proof of the criterion which divides the GL2(ℂ)-orbits of binary forms.

Canonical Forms and Orbit Spaces of Linear Systems
IMA Journal of Mathematical Control and Information, 1986Since globally continuous canonical forms exist only for very special group actions we propose to look instead for canonical forms which yield continuous sections on appropriate cellular decompositions of the orbit space. In this expository paper we present some general results concerning these `cellular' canonical forms for various types of group ...

Perturbational crystal orbital theory in matrix form
Computational and Theoretical Chemistry, 2011In this paper a formalism, called perturbational crystal orbital theory, is proposed and examined. This formalism is based on a recent formulation of the perturbational molecular orbital theory in matrix form, and could be considered as an extension of it to periodic lattices.
