Field Theory on Noncommutative Space-Time and the Deformed Virasoro Algebra
M. Chaichian, A. Demichev, P. Presnajder
We consider a field theoretical model on the noncommutative cylinder which leads to a discrete-time evolution. Its Euclidean version is shown to be equivalent to a model on the com…

Quantum Field Theory on Noncommutative Space-Times and the Persistence of Ultraviolet Divergences
M. Chaichian, A. Demichev, P. Presnajder
We study properties of a scalar quantum field theory on two-dimensional noncommutative space-times. Contrary to the common belief that noncommutativity of space-time would be a key…
