Perturbative and Geometric Analysis of the Quartic Kontsevich Model

Johannes Branahl, Alexander Hock, Raimar Wulkenhaar

The analogue of Kontsevich's matrix Airy function, with the cubic potential $\mathrm{Tr}\left({\Phi }^3\right)$ replaced by a quartic term $\mathrm{Tr}\left({\Phi }^4\right)$ with the sa…
