Multiple Periodic Solutions with Fixed Period for N-body Type Problems

Using the equivariant Ljusternik-Schnirelmann theory,the estimates of the lower bound of functional values on collision sets and the estimates of the critical values for the variational functional,we obtain some results in the large concerning multiple geometrically distinct noncollinear periodic solutions of any fixed mininal period for a class of planar N body type problems.
