Corrigendum to “On a Class of Conjugate Symplectic Hermite–Obreshkov One-Step Methods with Continuous Spline Extension” [Axioms 7(3), 58, 2018]

Axioms, 2019
The authors of the above mentioned paper specify that the considered class of one-step symmetric Hermite-Obreshkov methods satisfies the property of conjugate-symplecticity up to order p + r , where r = 2 and p is the order of the method.

The Kepler Problem: Orbit Cones and Cylinders [PDF]

, 2012
Planetary orbits, being conic sections, may be obtained as the locus of intersection of planes and cones. The planes involved are familiar to anyone who has studied the classical Kepler problem.

Charged particle in Lie–Poisson electrodynamics

European Physical Journal C: Particles and Fields
Lie–Poisson electrodynamics describes the semi-classical limit of non-commutative U(1) gauge theory, characterized by Lie-algebra-type non-commutativity. We focus on the mechanics of a charged point-like particle moving in a given gauge background. First,

The Classical Limit of the Quantum Kepler Problem

, 2013
The classical limit of the quantum mechanical Kepler problem is derived by using a simple mathematical procedure recently proposed. The method is based both on Bohr’s correspondence principle and the local averages of the quantum probability distribution.

Generalized Kepler problems. I. Without magnetic charges [PDF]

Journal of Mathematical Physics, 2013
For each simple euclidean Jordan algebra V of rank ρ and degree δ, we introduce a family of classical dynamic problems. These dynamical problems all share the characteristic features of the Kepler problem for planetary motions, such as the existence of Laplace-Runge-Lenz vector and hidden symmetry.
