The `\curvearrowleft` symbol is used to represent a curved arrow pointing to the left. It is often used in mathematical contexts to indicate a transformation or operation that is applied in a cyclic or iterative manner, or to denote a return to a previous state or position.
Indicating a transformation from B back to A in a cyclic process.
A \curvearrowleft B
Denoting a function f that returns to a previous state g in an iterative process.
f(x) \curvearrowleft g(x)
Illustrating a sequence of operations where Z returns to Y and then to X.
