单词	periodic point
释义	periodic point Mathematics Given a function f:X→X of a set X, then x in X is a periodic point if the sequence $x, f (x), f^{2} (x), f^{3} (x), \dots$ eventually returns to x. (Here f^k(x) denotes k applications of f to x.) The least positive n such that fⁿ(x) = x is called the period of x and ${x, f (x), f^{2} (x), \dots, f^{n - 1} (x)}$ is called the orbit of x.
