Positive periodic solutions in neutral nonlinear differential equations
We use Krasnoselskii's fixed point theorem to show that the nonlinear neutral differential equation with delay \begin{equation} \frac{d}{dt}[x(t) - ax(t-\tau)]= r(t)x(t)- f(t, x(t-\tau)) \end{equation} has a positive periodic solution. An example will be provided as an application to our theor...

description |
We use Krasnoselskii's fixed point theorem to show that the nonlinear neutral differential equation with delay
\begin{equation}
\frac{d}{dt}[x(t) - ax(t-\tau)]= r(t)x(t)- f(t, x(t-\tau))
\end{equation}
has a positive periodic solution. An example will be provided as an application to our theorems. |
