2015年8月16日 · 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.

The difference between two (as it is mentioned in the linked answer, as well as in the answer by MathEnthusiast):

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.

And in my opinion Prior's symbolism comes as clearer here than writing {E$\alpha$$\beta$, $\alpha$} $\vdash$ $\beta$, since the "$\rightarrow$" symbol suggests that one transitions from the left-hand side to the right hand side. $\endgroup$ –
