In LaTeX, we can write


In plain TeX, we can do thing like


{\scashape max}.

But this method does not work inside $$. We cannot write

$T_{{\scshape max}}$

So is there any way to make it work?

$T_{\hbox{\scshape max}}$ should work … – Qrrbrbirlbel Mar 30 '13 at 20:39
Perhaps $T_{\hbox{\scriptsize\scshape max}}}$ – Aditya Mar 30 '13 at 20:41
@Qrrbrbirlbel that would make a textsize subscript though. – David Carlisle Mar 30 '13 at 21:07
@Aditya \scriptsize isn't in plain. – David Carlisle Mar 30 '13 at 21:08
@DavidCarlisle Yes, it was more of a pointer than a solution. Op didn’t define any other fonts to use … – Qrrbrbirlbel Mar 30 '13 at 21:09

enter image description here

    \font\scshapevii=cmcsc10 at 7pt
    \font\scshapev=cmcsc10 at 5pt


$    {\fam\scfam Max}(T) = T_{\fam\scfam Max} $

Without defining a math family:

\font\sevensc=cmcsc10 at 7pt
\font\fivesc=cmcsc10 at 5pt


$\mathsc{Max}(T) = T_\mathsc{Max}$
