	 				<ce:simple-para id="SP0005" view="all">By studying the representations of the mapping class groups which arise in 2D conformal theories we derive some restrictions on the value of the conformal dimension <ce:italic>h</ce:italic><ce:inf loc="post">i</ce:inf> of operators and the central charge <ce:italic>c</ce:italic> of the Virasoro algebra. As a simple application we show that when there are a finite number of operators in the conformal algebra, the <ce:italic>h</ce:italic><ce:inf loc="post">i</ce:inf> and <ce:italic>c</ce:italic> are all rational.
