Abstract

In this paper, the problem of existence of homoclinic solutions is studied for the second-order singular differential equation

$$\begin{aligned} x''(t)+f(x(t))x'(t)-g(x(t))-\frac{\alpha (t)x(t)}{1-x(t)}=h(t), \end{aligned}$$

where \(f,g,h,\alpha : R\rightarrow R\) are continuous and \(\alpha (t+T)\equiv \alpha (t)\) for all \(t\in R\). Using the continuation theorem of coincidence degree theory given by Mawhin and Manásevich, a new result on the existence of homoclinic solutions to the equation is obtained.
