Homotopy of posets, net-cohomology and superselection sectors in globally hyperbolic spacetimes
Giuseppe Ruzzi
We study sharply localized sectors, known as sectors of DHR-type, of a net of local observables, in arbitrary globally hyperbolic spacetimes with dimension . We show that t…

Punctured Haag duality in locally covariant quantum field theories
Giuseppe Ruzzi
We investigate a new property of nets of local algebras over 4-dimensional globally hyperbolic spacetimes, called punctured Haag duality. This property consists in the usual Haag d…
