The existence of periodic solutions for nonconservative superlinear second order ODEs: a rotation number and spiral analysis approach

We investigate the existence of periodic solutions for nonconservative superlinear second-order differential equations in the sense of rotation numbers. Specifically, we focus on equations whose solutions at infinity behave comparably to a suitable linear system. By employing a rotation number appro...
