We study cubic polynomial differential systems having an isochronous center and an inverse integrating factor formed by two different parallel invariant straight lines. Such systems are time-reversible. We find nine subclasses of such cubic systems, see Theorem 8. We also prove that time-reversible

This paper deals with the pseudo-isochronicity for a class of septic differential systems. In this paper, we transform infinity into the origin so that the properties of infinity can be investigated with the methods developed for finite critical points. By calculating the singular point quantities a
## Abstract In this paper, we are concerned with the problem of boundedness of solutions for the second order differential equation __x__ β³ + __f__ (__x__ )__x__ β² + __g__ (__x__ ) = __e__ (__t__ ), where __f__ , __g__ β __C__ ^β^(β) are odd functions and __e__ (__t__ ) β __C__ ^β^(β/β€) is odd.
