Dear all, After I choose the module of Theorem in using LyX, there is conflict between the theoremstyle of LyX’s module and that in .cls.
LaTeX Error: Command \theoremstyle already defined. Is there anyone can give me some hints to solve this conflict? I don’t want delete the theoremstyle in .cls as it is required for submission to journal. Thank you so much. Best Regards, KC Cao
