    This paper contains some results on the stability of periodic solutions for equations of the type NEWLINE\[NEWLINEx''+h(t)x'+g(t,x)=0,NEWLINE\]NEWLINE where \(h\) and \(g(\cdot ,x)\) are \(2\pi\)-periodic and NEWLINE\[NEWLINE\int_0^{2\pi} h(t)\,dt =0.NEWLINE\]NEWLINE Some of the known techniques for \(h=0\) are adapted to this setting.
