Title: Null controllability of a population dynamics with interior degeneracy,
Abstract: In this paper, we deal with the null controllability of a population dynamics
model with an interior degenerate diffusion. To this end, we proved first a new
Carleman estimate for the full adjoint system and afterwards we deduce a
suitable observability inequality which will be needed to establish the
existence of a control acting on a subset of the space which lead the
population to extinction in a finite time.
