The journal who owns aa.cls asks the authors to use usepackage[varg]txfonts. However, there is a clash between that package and amsmath to define openbox:



Command openbox already defined. vrulehfil}}


So, I just tried to shut the clash down using letopenboxrelax:



documentclass[onecolumn]aa

letopenboxrelax
letproofrelax
letendproofrelax

usepackage[varg]txfonts
usepackageamsthm

begindocument
test
enddocument


But the error isn't resolved. What is the right angle of attack to this problem?

  • You didn't tell what exact error you get, I guess a "control sequence already defined." So try letopenboxundefined etc. to actually make the command undefined instead of assigning the meaning of relax

  • @siracusa: I added the exact error (Command openbox already defined. vrulehfil}}) to the question. By the way, letopenboxundefined didn't resolve the issue.

you are undefining the commands while they are undefined, you need to undefine them after they are defined the first time so



documentclass[onecolumn]aa

usepackage[varg]txfonts

letopenboxrelax
letproofrelax
letendproofrelax


usepackageamsthm

begindocument
test
enddocument
