Debayan Maity holds a Postdoctoral position at the ERC Advanced Grant project DyCon under the supervision of Prof. Enrique Zuazua (UAM and DeustoTech). Before that, he was a Post-Doctoral researcher at the Institut de Mathématiques de BordeauxI under the supervision of Prof. Marius Tucsnak. His main research interests are the fluid-solid interaction problems and the control of partial differential equations, namely fluid motions, population dynamics models, etc.
In this tutorial, we investigate the linear infinite dimensional system obtained by implementing an age structure to a given linear dynamical system. We show that if the initial system is null controllable in a time small enough, then the age structured system is also null controllable in a time depending on the various involved parameters.
