I'm writing an article for representation theory and I want to type downward arrow for restriction and upward arrow for induction. The $\downarrow$ and $\uparrow$ give arrows that aren't right next to the letters. E.g.

enter image description here

I want the arrows to be right next to the letters, for example enter image description here

Does anyone know which command I should use? Thanks!

    You can always reduce the space: \!, etc.

Surround \downarrow by {...}.



enter image description here

\downarrow is a relation symbol, putting it within {...} make it be treated as it belongs to the "ordinary" class.

As suggested by egreg, the same result can be achieved more elegantly using \mathord:




  • Yes: \downarrow is a relation symbol. I think it would be better to define \newcommand{\restr}{\mathord\downarrow} and \newcommand{\ind}{\mathord\uparrow}
