Subtext in latex

**Bucephalus** · April 22nd 2009, 09:57 PM

How do I post in latex the subtext under some formulas.
For example
http://www.m-hikari.com/ija/forth/dr...JA5-8-2009.pdf
Go to page 233 of this document and there are formulas with
"max" for example, and under the "max" there is subtext.
Just look at the $||A||_{1\infty}$ norm and you see that there are conditions under the "max" to the effect of $(i,j)|\in......$ .
How do I put this under the $max$ ?

regards
Bucephalus

[tex]\max\limits_{(i,j)\in\dots}[tex] generates $\max\limits_{(i,j)|\in\dots}$ .

Note that \limits is also useful in putting subscripts under double and triple integrals!

i.e. $\iint\limits_R f\!\left(x,y\right)\,dA$ or $\iiint\limits_G f\!\left(x,y,z\right)\,dV$

$\max_{j=1 ....}$ = \max_{j=1 ....}

Can I improve on this?

$||A||_{(1,\infty)}=^{max}_{(i,j)|\in\{1,.....,m\}\ times\{1,.....,n\}}|a_{ij}|$

Thanks

Thanks

[tex]||A||_{(1,\infty)}=\max\limits_{(i,j)|\in\{1,\dots ,m\}\times\{1,\dots,n\}}|a_{ij}|[/tex]

OR

[tex]||A||_{(1,\infty)}=\max_{(i,j)|\in\{1,\dots,m\}\ti mes\{1,\dots,n\}}|a_{ij}|[/tex] gives:

$||A||_{(1,\infty)}=\max\limits_{(i,j)|\in\{1,\dots ,m\}\times\{1,\dots,n\}}|a_{ij}|$ or $||A||_{(1,\infty)}=\max_{(i,j)|\in\{1,\dots,m\}\ti mes\{1,\dots,n\}}|a_{ij}|$ respectively.

That's exactly what I'm looking for.
Thanks for your help, both of you.

once again, thanks Chris.

@ Bucephalus : there's also this one :

[tex]\underset{ (i,j)|\in\{1,\dots,m\}\times\{1,\dots,n\} }{\max}|a_{ij}|[/tex]

$\underset{ (i,j)|\in\{1,\dots,m\}\times\{1,\dots,n\} }{\max}|a_{ij}|$
