A Remark On Field Theories On The Non-Commutative Torus

High Energy Physics - Theory 2007-05-23 v1

Abstract

We investigate field theories on the non-commutative torus upon varying theta, the parameter of non-commutativity. We argue that one should think of Morita equivalence as a symmetry of algebras describing the same space rather than of theories living on different spaces (as is T-duality). Then we give arguments why physical observables depend on theta non-continuously.
