This should be a usual lim, with a left-pointing arrow under it, and it should be a "math operator with limits", that is, one should be able to write something like \ilim_n and get lim <-- n with, of course, the right spacing and so on. this can be done quite easily, building on the existing ams-latex definition \varinjlim: \newcommand{\ilim}{\mathop{\varinjlim}\limits} using it: \[ abc \ilim_n def \] of course, as in-line text, the lower limit will appear in subscript position. -- bb ------------------------------ Date: Fri, 23 Jul 1999 10:06:54 -0400 From: "Fernando Q.

There's always something really easy one has missed! You mean \varprojlim, but this solution does seem to work fine. I've been using the following ugly hack: \newcommand{\ilim}[1]{\displaystyle\lim_{\xleftarrow[\hidewidth\scriptstyle #1\hidewidth]{\hphantom{\mathrm{iii}}}}} which puts the arrow a bit lower than does \varprojlim. I'll have to experiment with both versions to see. bb> of course, as in-line text, the lower limit will appear in subscript bb> position. So one probably should just throw in a \displaystyle into the definition (at least for my taste!). Fernando - -- Fernando Q.

I have seen papers where a broken direct sum sign is used, for instance. Thanks!

I'm after something that I can give a definition of a structure to, and have it draw a little box depicting the struct, with fields in it linked (i.e. pointing to) another struct box? I imagine I could build something like this myself with pstricks, but I wondered if it had already been done. best regards, Calum. ------------------------------ End of TeXhax Digest V1999 #8 ***************************** About TeXhax...
