[A research prompt written for a chatbot: investigate every case in semiotics of a third-order derivative, f''' = f, where differentiation may be used literally but may also be read in the Deleuzian sense; examine how this connects to f''' = f in mathematics; compare f''' = f acting on a single solution (x) with f'''(x, y, z) = f(x, y, z) acting on three variables that are entangled with one another; ask whether the former has been interpreted in semiotics, and the latter; and ask whether, in the latter case, the stable structure of signs (a structure that evolves stably by itself through f''' = f) can be challenged more strongly (a collision of several different fields). Answer semiotically and philosophically, and also mathematically and physically.]

The connection between dynamics, differential equations and topology.
