How are Feynman graphs resumed by the Loop Vertex Expansion?
Vincent Rivasseau, Zhituo Wang
The purpose of this short letter is to clarify which set of pieces of Feynman graphs are resummed in a Loop Vertex Expansion, and to formulate a conjecture on the theory in n…

Quantum Field Theory on quantized Bergman domain
Harald Grosse, Peter Prešnajder, Zhituo Wang
We present an oscillator realization of discrete series representations of group SU(2,2). We give formulas for the coherent state star-product quantization of a Bergman domain .…

Loop Vertex Expansion for Phi^2k Theory in Zero Dimension
Vincent Rivasseau, Zhituo Wang
In this paper we extend the method of loop vertex expansion to interactions with degree higher than 4. As an example we provide through this expansion an explicit proof that the fr…
