Abstract: This seminar is divided in two parts. The firs will report on results about quantized control systems, i.e. systems controlled with inputs from finite alphabets. In particular we will show how to introduce quantization on purpose for planning. The second part will focus on a new mathematical framework to deal with motion of intelligent groups. Based on time evolving measure the framework permits to address the problem both from macroscopic point of view, with application to pedestrian motion, and microscopic one, with application to animal groups.
