Constructive Renormalization of 2-dimensional Grosse-Wulkenhaar Model [PDF]
Zhituo WangIn this talk we briefly report the recent work on the construction of the 2-dimensional Grosse-Wulkenhaar model with the method of loop vertex expansion. We treat renormalization with this new tool, adapt Nelson's argument and prove Borel summability of the perturbation series. This is the first non-commutative quantum field theory model to be built in a non-perturbative sense.View original: http://arxiv.org/abs/1205.0196
