A counterclockwise circular arrow symbol representing cyclic operations, inverse rotations, or leftward group actions in algebra.
Examples
Cyclic group action
G \circlearrowleft X \text{ denotes a left group action of G on X}
Counterclockwise contour integral
\oint_{\gamma} f(z)\,dz = \int_{\circlearrowleft} f(z)\,dz
Rotation operator in physics
R_{\circlearrowleft}(\theta) \text{ rotates vector } \vec{v} \text{ by angle } \theta
