In a beamer frame I can't change the fontsize in a box (minipage or parbox): LaTeX Error: Bad math environment delimiter. You can't use `\eqno' in restricted horizontal mode. Outside the box it works. How can I achieve this?(I have a model as a graphics on the left; to the right the equations should be shown. In normal fontsize they would be too long; therefore I wanted a small fontsize)
