“…It is well-known that (E, f) is topologically conjugated to the subsystem of (2 E , 2 f ) that consists of the singleton sets of E when E satisfies certain conditions and an appropriate hyperspace topology is selected, e.g., hit-or-miss topology (see [28][29][30]) or Vietoris topology (see [3,16,36]). Clearly, an invariant subset of the original system (E, f) becomes a fixed point of the hyperspace system (2 E , 2 f ).…”
