Group Generated by $1 / z$ and $-z$
Let:
- $S = \set {f_1, f_2, f_3, f_4}$
where $f_1, f_2, f_3, f_4$ are complex functions defined for all $z \in \C \setminus \set 0$ as:
\(\ds \map {f_1} z\) | \(=\) | \(\ds z\) | ||||||||||||
\(\ds \map {f_2} z\) | \(=\) | \(\ds -z\) | ||||||||||||
\(\ds \map {f_3} z\) | \(=\) | \(\ds \dfrac 1 z\) | ||||||||||||
\(\ds \map {f_4} z\) | \(=\) | \(\ds -\dfrac 1 z\) |
Let $\circ$ denote composition of functions.
Then $\struct {S, \circ}$ is the group generated by $\dfrac 1 z$ and $-z$.
