Abstract

The purpose of this paper is to introduce the concept of observability for distributed hyperbolic systems evolving in spatial domain Ω. It consists of the reconstruction of the initial conditions, on a subregion Γ of ∂Ω, that the initial state and speed are to be observed between two prescribed functions given only on the boundary subregion G. We give some definitions and properties of this kind of observability and we describe two approaches to solve this problem which the first is based on subdifferential techniques and the second one uses the Lagrangian multiplier method. This last approach leads to an algorithm which is implemented numerically and illustrated through an example and numerical simulation. © CSP - Cambridge, UK; I&S - Florida, USA, 2018.
