The style file probably uses \MakeUppercase{...} to force the letters into uppercase. You should be able to override it by fixing the letters in lowercase in a saved box then use that box in the title. Whatever you put in a saved box cannot be split a across a line break. \documentclass{minimal} \begin{document} \newsavebox{\abc} \savebox{\abc}{abc} \MakeUppercase{abc} % this will be changed to uppercase \MakeUppercase{\usebox{\abc}} % this stays in lowercase \end{document}
