報告摘要:

It is nowadays understood that, for engineering systems the stability of solution in classical (Lyapunov) sense is not enough for practical purposes, since the solution may have a basin of attractions very narrow and such that even small imperfections/disturbances may lead the system to another coexisting solution, commonly representing an engineering unwanted outcome for the system. It is not only a matter of smallness of basins of attraction, as the basin may be large but very fractal, with only a small compact part. The investigation of this topic, which consists of determining the robustness of the solution, or its "practical stability", is named dynamical integrity and entails investigating the properties of safe basin. It is the object of this presentation.
