Abstract
We prove the existence of infinitely many subharmonic solutions (with a precise nodal characterization) to the equation (Formula presented.), in the unforced case g(t,0) ≡ 0. The proof is performed via the Poincaré-Birkhoff fixed point theorem. © Springer Science+Business Media New York 2013
