The paper considers quasi-nonliner differential-difference equations (DDE) of the form which is a representative example of so-called completely integrable DDEs (i.e., DDEs that are reducible to functional equations). This equation is shown to exhibit the "nonstandard" (from the viewpoint of ...
In engineering problem, the problem of controlling the temperature in a reaction tank is addressed using differential difference equations. The temperature variation is reported because of random disturbances, inherent effects due to u being non-zero, and the operation of the control device. The ...

Maybe for the first time in the existing literature, we investigate here the almost periodic type solutions to the abstract Volterra difference equations depending on several variables. We also investigate the generalized almost periodic type sequences and their applications in a rather detailed manner ...

We examine a family of integrable differential-difference equations and obtain their non-autonomous extensions using a discrete/continuous integrability criterion. Introduction Integrable deautonomization of difference equations have been the object of intensive studies these past few years, in particular in...
