The differential equations I want to solve is $$ \frac{\partial c_0(t)}{\partial t}=-\frac{1}{2} \kappa c_0(t)-\kappa \sum _{n=1}^N \alpha ^n c_0(t-\text{n$\tau $}) e^{i n \phi _{\tau }} \Theta (t-\text{n$\tau $}) $$ Here $\Theta(t)$ is the step function, $N$ is determined by $N=Integer[\frac{tmax}{\tau}]$. This equation has multipile time delays. By solving this equation, I think there may be chaos in this equation for certain parameters. evofback[\[Tau]_, m_, \[Alpha]_, \[Phi]_, tlist_, cin...
