A solvable QFT in 4 dimensions
and my interactions with "Jurko" Glaser

Vrijeme: 14 sati c.t.
Mjesto: IRB, predavaona III krila
Sazetak:
I first remark on the time I spent at CERN and my interactions
with Glaser, from whom I learnt a lot about 2 D solvable QFT models.
Afterwards I review my common work with Raimar Wulkenhaar
on 4 D models:
The regularisation of a scalar field on Moyal space leads to a
matrix model. All correlation functions obey solvable singular
integral equations (which I learnt to treat from Glaser).
The two point function is solved by a NONLINEAR integral equation.
We obtained a 4 D QFT, which satisfies growth property, covariance and
symmetry. We discuss the evidence for reflection positivity for
the 2-point function, for a certain range of the coupling constant.
