Some Remarks on Local Activity and Local Passivity [PDF]
International Journal of Bifurcation and Chaos, 2017 We study local activity and its contrary, local passivity, for linear systems and show that generically an eigenvalue of the system matrix with positive real part implies local activity. If all state variables are port variables we prove that the system is locally active if and only if the system matrix is not dissipative. Local activity was suggested
