Infinitely Many Periodic Solutions for Some N-Body Type Problems with
Fixed Energies    [PDF]

Pengfei Yuan, Shiqing Zhang

In this paper, we apply the Ljusternik-Schnirelman theory with local Palais-Smale condition to study a class of N-body problems with strong force potentials and fixed energies. Under suitable conditions on the potential $V$, we prove the existence of infinitely many non-constant and non-collision symmetrical periodic solutions .
