Random lattice strings vs. type IIB matrix models

TL;DR

This paper explores a potential connection between Siegel's random lattice string model and the type IIB matrix model, suggesting that additional terms might be present in the latter beyond the weak coupling approximation.

Contribution

It proposes a possible overlooked aspect in the type IIB matrix model by comparing it with random lattice string theories.

Findings

Potential extra terms in the type IIB matrix model identified.

Comparison indicates a relation between string models and matrix models.

Highlights need for further investigation into the weak coupling limit.

Abstract

I comment on a curious relation between Siegel's model of random lattice strings and type IIB matrix model. The comparison of the two theories suggests that there may exist extra terms in the latter which are overlooked in the weak string coupling limit.
