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} usepackage{amsthm} begin{document} test end{document} But the error isn't resolved. What is the right angle of attack to this problem?
amsmath txfonts
