# 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. –  Peter Grill Jan 19 '13 at 9:52
no no, its for normal equations –  Los WochoS Jan 21 '13 at 9:24

Please remember that (La)TeX was designed carefully by people who know much, much more than we'll ever learn about typesetting. Changing such rather common constructions is ill-advised. Maybe in some specific case the default isn't ideal.

I agree with this answer - I've worked in mathematics and physics for a long time, and the standard spacing is the norm. You might also like to read the comments on a similar question here –  John Hammersley Jan 19 '13 at 1:31
generally i'm not trying to change the common constructions, but in my case i thought it was looking better. i will use the standard spacing then. thanks for the answers –  Los WochoS Jan 21 '13 at 9:28
