Abstract
This is an exposition of joint work with S. Doplicher, K. Fredenhagen, and G. Piacitelli on field theory on the noncommutative Minkowski space [1]. The limit of coinciding points is modified compared to ordinary field theory in a suitable way which allows for the definition of so‐called regularized field monomials as interaction terms. Employing these in the Hamiltonian formalism results in an ultraviolet finite S‐matrix.
