## Abstract This is an exposition of joint work with S. Doplicher, K. Fredenhagen, and Gh. Piacitelli [1]. The violation of unitarity found in quantum field theory on noncommutative spacetimes in the context of the soβcalled modified Feynman rules is linked to the notion of time ordering implicitly
## Abstract We give the main ideas our proof that the noncommutative Ο^4^βmodel is renormalisable to all orders. Compared with the commutative case, the bare action of relevant and marginal couplings contains necessarily an additional term: an harmonic oscillator potential in the free field action
