Hello everyone,

Suppose that I am defining a function which embeds a surface (manifold) in $\mathbb{R}^3$.

Is there a standard symbol or letter that is used for this function?

Additionally, is there any other classical or standard notation (such as the hooked arrow for inclusion maps) of which I ought to be aware?

Regards,

Christopher

Most embeddings I've met were called a lower case Roman letter between $e$ and $k$. As far as arrows, I prefer $\hookrightarrow$ for an embedding and $\looparrowright$ for an immersion, but you sometimes also see $\subset$ for an embedding and $\subseteq$ for an immersion. –  Mark Grant Aug 13 '12 at 12:30

I usually use $\iota$ (\iota) for all kinds of embeddings.

No, there is none.

Thanks Dox, I hadn't run into anything obviously standard in the literature, but I wanted to ask before I put it in my thesis! –  Christopher Laing Aug 15 '12 at 0:00
    
You're welcome! (even if mine contribution was useless) –  Dox Aug 15 '12 at 1:55
