G. Fusco et Wm. Oliva, INTEGRABILITY OF A SYSTEM OF N ELECTRONS SUBJECTED TO COULOMBIAN INTERACTIONS, Journal of differential equations, 135(1), 1997, pp. 16-40
The Liouville integrability of a system of N repelling particles in R(
n), for a large class of potentials, is obtained by showing that the a
symptotic velocities are smooth first integrals, independent, and in i
nvolution. A new proof for the existence of the asymptotic velocities
is also presented. (C) 1997 Academic Press.
