Forced oscillations for delay motion equations on manifolds
Electronic journal of differential equations, Tome 2007 (2007)
We prove an existence result for $T$-periodic solutions of a $T$-periodic second order delay differential equation on a boundaryless compact manifold with nonzero Euler-Poincare characteristic. The approach is based on an existence result recently obtained by the authors for first order delay differential equations on compact manifolds with boundary.
