Matrix Models and String World Sheet Duality

TL;DR

This paper argues that the agreement between matrix model calculations and supergravity results can be understood as a consequence of string world sheet duality, based on a specific scaling limit and analyticity assumptions.

Contribution

It provides a theoretical framework linking matrix models and string world sheet duality, clarifying the underlying reasons for their agreement.

Findings

Matrix models can be derived using a particular scaling limit.

String world sheet duality explains the agreement with supergravity.

Analyticity assumptions are crucial for the argument.

Abstract

The scaling limit used recently to derive matrix models, and a certain analyticity assumption, are invoked to argue that the agreement between some matrix model calculations and supergravity is a consequence of string world sheet duality.
