# Space between letter and lowercase in latex math mode

is there a way to remove the space between the variable and the lowercase letter as standard in math environment?

by now i'm using this:

$$a\;b_{\! c}\;d$$


Without \! the space looks to big. Now i thought, if it is possible to set this by default in the math environment.

• The spacing without the \! seems correct for the product. If you are looking for more of a row vector, see if \begin{matrix} a & b_{c} & d \end{matrix} is more to your liking. Jan 19, 2013 at 9:52
