Continuum limit of fishnet graphs and AdS sigma model

A bstractWe consider the continuum limit of 4d planar fishnet diagrams using integrable spin chain methods borrowed from the N$$ \mathcal{N} $$ = 4 Super-Yang-Mills theory. These techniques give us

On the large N expansion in hyperbolic sigma-models

Invariant correlation functions for ${\rm SO}(1,N)$ hyperbolic sigma-models are investigated. The existence of a large $N$ asymptotic expansion is proven on finite lattices of dimension $d \geq 2$.

We give a Lagrange formulation of the gauge invariantn-orbital model for disordered electronic systems recently introduced by Wegner. The derivation proceeds analytically without use of diagrams, and
