[Tex/LaTex] Math letter’s italic correction


Are there a way to display PS and TN and CD and so forth (product of two variables) more beautifully? The normal CM font puts a wide space between the left letter and right letter.

If use the package txfonts the $S_1$ turned not so good-looking.

I've nothing to do with txfonts (more exactly, txmi family). Maybe you can use another Times like font package. mathptmx works fine (but it has fewer symbols than txfonts), and if you use XeTeX, you can also use XITS Math for math fonts. Commercial fonts like MathTimePro(2) are also good-looking.

I suggest XITS Math with XeLaTeX:

\setmathfont{XITS Math}
See $S_1$, $S_2$, $S_3$.
