Extended Complex Plane
- $\overline \C$
The extended complex plane $\overline \C$ is defined as:
- $\overline \C := \C \cup \set \infty$
that is, the set of complex numbers together with the point at infinity.
The $\LaTeX$ code for \(\overline \C\) is \overline \C
or \overline {\mathbb C}
or \overline {\Bbb C}
.
Variant
The variant $\C_\infty$ can often be seen:
- $\C_\infty$
- $\C_\infty := \C \cup \set \infty$
The $\LaTeX$ code for \(\C_\infty\) is \C_\infty
or \mathbb C_\infty
or \Bbb C_\infty
.
