A periodic point of period $m$ is a point that returns to itself after $m$ iterations of the function. The video emphasizes that this is recurrence under repeated application of $f$, not the same notion of period used for trigonometric functions.

Conditions: $f$ is a function under consideration.; $m$ is a positive integer counting the number of iterations.; $p$ is a point for which the iterates are defined.
