Regional Boundary Strategic Sensors Characterizations

This paper, deals with the linear infinite dimensional distributed parameter systems in a Hilbert space where the dynamics of system is governed by strongly continuous semi-groups. More precisely, for parabolic distributed systems the characterizations of regional  boundary strategic sensors have been discussed and analyzed in different cases of regional  boundary observability in infinite time interval. Furthermore, the results so obtained are applied in two-dimensional systems and sensors studied under which conditions guarantee regional boundary observability in a sub-region of the system domain boundary.  Also, the authors show that, the existent of a sensor for the diffusion system is not strategic in the usual sense, but it may be regional  boundary strategic of this system
