It might be that I am missing something here. But I don not understand why in the math expression below the spacing behind the letters is different. With this behaviour it seems impossible to name a variable PYR and have it typeset as such.

If you need to have a variable PYR, you should probably do \def\PYR{PY\kern-2ptR} $\PYR$ (modify kerning at your own will; you might also want to use em instead of pt units, or you could use \! if you don't need to be too accurate) The extensive original spacing is most probably related to the fact that in mathematics you usually mean multiplication when you write one letter after the other. In other cases (for example when you have a function like "sin", "cos", "lim", ...) the spacing will look better. Still, the fact that there is such a huge difference between PY and YR looks more like a tiny font bug to me (but it is already present in CM, so LM is unlikely to change it, at least until they switch to OpenType Math).

However, I think that in the example given by Hans VdM in mkiv, there is another, more important, issue which is the way the commas are treated between the variables Q, Y, N, P, Y, Z in math italic. Please compare the following outputs, one obtained with mkii and the other with mkiv: http://dl.dropbox.com/u/4316076/spacing-mkii.pdf http://dl.dropbox.com/u/4316076/spacing-mkiv.pdf I think that this is a big issue in typesetting maths with mkiv since punctuations are treated in an incorrect way. Best regards: OK PS: Sorry for the delay… yesterday this message was rejected when sent with the attached PDFs, because it was over 64Kb.

It seems to me that the effect of the above command is to modify the spacing between characters and punctuation marks, but still the latter are misplaced with LM math fonts (with \bf or \rm there is no problem).
