This category contains results about Circle Group.


Let $K$ be the set of all complex numbers of unit modulus:

$K = \set {z \in \C: \cmod z = 1}$

Consider the algebraic structure $\struct {K, \times}$ where $\times$ denotes the operation of complex multiplication.


Then $\struct {K, \times}$ is called the circle group.
