Null Controllability of a Nonlinear Dissipative System and Application to the Detection of the Incomplete Parameter for a Nonlinear Population Dynamics Model

Abstract EN

We first prove a null controllability result for a nonlinear system derived from a nonlinear population dynamics model.

In order to tackle the controllability problem we use an adapted Carleman inequality.

Next we consider the nonlinear population dynamics model with a source term called the pollution term.

In order to obtain information on the pollution term we use the method of sentinel.
