\\lesssim for iopart.cls?

Post by Pier Stefano Corasaniti » August 16 2005

Hi,
I have a very silly problem...but it is distressing me quite a lot,
I am editing in IOP style (JCAP for the aficionados), I used the command lesssim (here we go \lesssim), but the .cls and .sty files downloaded from the JCAP website do not seem to have any definition of it..at most they have \lsim for what is (\sim) in revtex4...does anyone has a clue about how to sort it out?

Perhaps is easier if I submit to another journal which allow \lesssim...it is so crucial...;0)
Regards,

Pier-Stefano

I think if you include the iopams.sty file in addition to iopart.cls, \lesssim should work. \lesssim is an AMS-ism, as I recall, and iopams.sty mostly just includes all the AMS packages.
