“…The early work on this subject was motivated by the observation of relaxation oscillations in electrical circuits [65,66,67]. Later, slow-fast dynamics found applications in a wide range of problems such as chemical reactions [68,69,70,71,72], excitable systems (e.g., neural networks) [73,74,75,76,77,78,79], extreme weather patterns [80,81,82], and dynamics of finite-size particles in fluid flows [83,84].…”
