Stochastic quantization of $\lambda {\varphi }_2^4$- theory in 2-d Moyal space

Chunqiu Song, Hendrik Weber, Raimar Wulkenhaar

There is strong evidence for the conjecture that the $\lambda {\varphi }^4$ QFT- model on 4-dimensional non-commutative Moyal space can be non-perturbatively constructed. As preparation, in this p…
