Re: la definizione di \maketitle è modificabile?

togliendo la @ in \def\maketitle a me funziona

`\makeatletter
\def\maketitle{%
\cleardoublepage \thispagestyle{empty}%
\begingroup \topskip\z@skip
\null\vfil
\begingroup
\LARGE\bfseries \centering
\openup\medskipamount
\@title\par\vspace{24pt}%
\def\and{\par\medskip}\centering
\@author
\par\bigskip
\vfill
\includegraphics[height=1cm]{figure/ARS_logo_colori_rifilato.jpg}
\endgroup
}
\makeatother`

oppure usando \renewcommand{\maketitle}
