Abstract Systems of time-delay differential equations are widely used to study the dynamics infectious diseases and immune responses. The Marchuk-Petrov model is one them. Stable non-trivial steady states stable periodic solutions this can be interpreted as chronic viral diseases. In work we briefly describe our technology developed for computing systems present discuss results with parameter v...

It is suggested that such vitreoretinal junction pathology may be responsible for the developmen...
