Modular Intersections of von-Neumann-Algebras in Quantum Field Theory

H.-W. Wiesbrock

We show that modular intersections of von-Neumann-algebras occur naturally in 2+1-dim. quantum field theory. An example is given by the local observable algebras of wedge regions with a common lightray in the vacuum sector, see also [Bo 2, Wi 3].
