What is wrong with redefining short commands, like L or AA?
• Such redefinitions preclude the use of the original meaning in, for example, the name of an author in a bibliography, possibly requiring input changes if this isn’t discovered until text input is well underway. • The most serious side effects occur when such commands are redefined in a job that also requests \usepackage{hyperref}. • If the redefinition includes math commands, in particular a special math font, a spurious error may be reported at every element that is hyperlinked, e.g. ! LaTeX Error: \xxx allowed only in math mode. • This prevents the LaTeX run from completing error-free. • It also obscures genuine errors in the job log, with the result that errors could be preserved in the final output. • When the document is an article to be published in an AMS journal, there are additional considerations: • All AMS journals are hyperlinked for on-line posting. • Automated production procedures require error-free LaTeX compilation. • The article top matter and bibliography are trans
