The Laplace-Runge-Lenz vector was extended to the case of arbitrary central-potential problems by Fradkin (1967) and, independently, by Peres (1979). The two methods of generalisation are investigated from a synthetic point of view, and shown to be identical to each other. 

Fradkin-Bacry-Ruegg-Souriau vector in kappa-deformed space-time

We study the presence of an additional symmetry of a generic central potential in the κ space-time. An explicit construction of Fradkin, Bacry, Ruegg and Souriau (FBRS) for a central potential is

The P availability enhancing properties of citric acid are not only due to acidification of the plant rhizosphere, but also to its Al and Fe complexing capacity.
