We considered a semilinear, second order periodic system. We assumed that the differential operator x → -x -Ax has zero as an eigenvalue and has no negative eigenvalues. Also we imposed a strong resonance condition (with respect to the zero eigenvalue) on the potential function F(t, x). Using the se
