Titolo:	CHARGED SUPERSELECTION SECTORS AND TOPOLOGY OF SPACETIMES
Abstract:	I will talk of a new kind of superselection sectors induced by the nontrivial topology of a curved spacetime. In particular, the localization, the charge structure, and the topological content of these superselection sectors will be discussed. The talk is based on a joint work (in progress) with Romeo Brunetti
