Abstract
Modeling ecological and environmental problems lead to the study of mathematical systems with missing data. In this paper we study a parameter identification question of a pollution problem using the method of sentinels by Lions (1992). Our system, which is a spatio-temporal one contains a missing initial condition.
We show that the question of existence of a sentinel insensitive to the initial condition is equivalent to an approximate null-controllability problem for which we present a variational method.
