This paper deals with the idea of the orthogonal functions in the equivalent linearization of the nonlinear systems. Block Pulse (BP) function gives effective t
This paper studies regional stabilization of a distributed bilinear system evolving on a spatial domainΩ. Sufficient conditions for regional weak, strong and e
The paper aims to extend the notion of regional observability of the gradient to the semilinear hyperbolic case, in order to reconstruct the gradient of the ini
