  • Klaus Fredenhagen

A consistent formulation of quantum field theory on noncommutative spacetimes is possible provided time ordering and Wick rotation are done in the appropriate way. The resulting Feynman rules differ from those obtained by formal analogy to the commutative case. The problem of renormalization is discussed.
