Abstract: 

In this seminar I will talk about two recent topics I worked on:

  1.  Certain models of NCQFT
  2. Construction of NC metric 

In the first part I will show you a scalar field theory and a certain gaugetheory on a deformed R^3 space, which are free of UV/IR mixing and even more,they are perturbativly finite, rendering the long forgotten dream ofnoncommutativity serving as a natural UV cut-off.In the second part I will elaborate on some recent results about construction of NC metric as a parallel to what was found in E.Beggs, S.Majid "Gravity induced from quantum spacetime", Class.Quant.Grav 31 (2014) 0305020.
