Abstract
We show that the periodically perturbed N-dimensional relativistic pendulum equation has at least N + 1 geometrically distinct periodic solutions Also we obtain the existence of infinitely many solutions for systems with oscillating potential Both results are obtained by reduction to an equivalent non-singular problem using classical critical point theory.
