Is there a standard name for the bijection between $\mathbb{R}^2$ and $\mathbb{C}$?

Question

Is there a frequently used letter (name) to denote the obvious bijection $(x,y)\mapsto x+iy$ from $\mathbb{R}^2$ to $\mathbb{C}$?

Answer 1

No there is no standard name for the bijection \begin{align} \mathbb R^2 &\to\mathbb C\\ (x,y)&\mapsto x+yi.\end{align} It is assumed that everyone understands that $\mathbb C$ is a two-dimensional vector space over $\mathbb R$, so no one ever explicitely writes down this bijection. In fact, I can't even think of a situation where there would be a need to.
