Apr 6, 2014 · I am currently using $$\phi(\varepsilon) \overrightarrow{ \varepsilon \rightarrow 0 }0 $$ for writing down mathematical limits.

Aug 16, 2015 · However, $\xrightarrow{dim}$ puts the arrow in the centre (as one would have for a map) which makes the dim small and doesn't look good. So is there an arrow which works like a $\widehat{dim}$ but with an arrow instead of a hat? P.S. The text I'm using just uses an underline but I feel it isn't noticeable enough.

Apr 13, 2016 · Difference of mapsto and right arrow (3 answers) Closed 8 years ago. Can someone explain the difference ...

To me this is the simplest and most flexible solution, and renders nicely too (sure, it does not look like the right arrow in math mode but for many purposes it might be enough). You can control spacing very easily inside the verbatim. For instance, more spacing would be A \verb| -> | B. Both are shown below.

Apr 20, 2016 · the notation $\mapsto$ ("maps to", an arrow with a bar at its tail) ... There is another arrow-symbol, which also used for mapping $\rightarrow$, which might be a bit confusing. The difference between two (as it is mentioned in the linked answer, as well as in the answer by MathEnthusiast):

I'm doing Project Euler Question 14 and would like to know what the right arrow → means in: n → n/2 (n is even) n → 3n + 1 (n is odd) I gather from the phrasing of the question that it has to do with set theory. Any links to primers on set theory that would help me to understand the question greatly appreciated. Thanks.

Aug 8, 2012 · I would like to know what is the best way to do an inclusion arrow, using xy or tikz. I know that there is a command for an arrow, like \\to, for inclusions, but this is not expansible. What do yo...

The second line uses \Longrightarrow and is better, but there's not enough space to set the arrow apart from the surrounding symbols (the two inequalities are spaced as much as the arrow). Finally, in the third line (which uses \implies), the additional space highlights the arrow from the rest and so improves the readability of the formula.
