%T Exact observability of nonstationary hyperbolic system with scanning finite-dimensional observations
%U https://pure.iiasa.ac.at/id/eprint/13596/
%X We consider the problem of exact observability of the linear hyperbolic equation with time-varying coefficients under internal finite dimensional moving observations. Two types of scanning observations are considered and the existence of spatial curves and set-valued maps for sensors that ensure exact observability is established. The techniques involved are related to the construction of suitable skeletons for required observation curves and maps
