Mapping
- $\map \chi x$
The Greek letter $\chi$, along with $\psi$ and $\phi$ and others, is often used to denote a general mapping.
In the context of abstract algebra, it often denotes a homomorphism.
The $\LaTeX$ code for \(\map \chi x\) is \map \chi x .
Linguistic Note
The name of the Greek letter $\chi$ (chi) is pronounced khi, where:
- the kh sound is as the ch in the German ich, or in the Scots word loch
- the word rhymes with by.
If this causes difficulties, the pronunciation ki or hi are sometimes considered acceptable alternatives.
Under no circumstances is it correct to pronounce it tshi or shi.
