A DECISION FUNCTIONAL FOR MULTITIME CONTROLLABILITY

This paper refers to multitime linear normal PDE systems from controllability point of view. The ideas presented here are complementary to those in our most recent papers and contain original results on multitime controllability, based on the γ- gramian matrix, the Im-gramian space and a controllability functional. Some original examples emphasize the utility and novelty of the theoretical results having in mind possible applications to control and signal processing, circuits, image processing, computer tomography, seismology etc.
