Abstract
In a previous paper we discussed simple examples like particle on a circle and molecules to argue that mixed states can arise from anomalous symmetries This idea was applied to the breakdown anomaly of color SU3 in the presence of nonabelian monopoles Such mixed states create entropy as wellIn this article we extend these ideas to the topological geons of Friedman and Sorkin in quantum gravity The “large diffeos” or mapping class groups can become anomalous in their quantum theory as we show One way to eliminate these anomalies is to use mixed states thereby creating entropy These ideas may have something to do with black hole entropy as we speculate
