Lupanov representation

The Lupanov representation typically refers to a mathematical framework related to the study of evolving dynamical systems, often in the context of stability analysis or control theory. The term "Lupanov" might be a misspelling or variation of "Lyapunov," which is a well-known name associated with Lyapunov stability theory. Lyapunov's work primarily deals with determining the stability of equilibrium points in dynamical systems.
