# [Tex/LaTex] Limits under multiple \sum

math-modemath-operators

I would like to place a lower limit under two consecutive \sums, somewhere in between. So I have \sum_{j=1}^{\infty}\sum_{k=1}^{\infty} and would like to place j>k in the lower limit between the two sums. I believe the multiple integral operator has this kind of functionality.

Something like:

\mathop{\sum_{j=1}^{\infty}\sum_{k=1}^{\infty}}_{j>k}

maybe?

Looks like this:

Or if you want it on the same line as j=1 and k=1, then maybe:

\mathop{\sum^{\infty}\sum^{\infty}}_{j=1\ j>k\ k=1}
