String Field Theories from One Matrix Models

TL;DR

This paper derives the string field theory equations from the continuum limit of a one matrix model, confirming their consistency with recent background independent formulations.

Contribution

It establishes a connection between one matrix models and string field theories through the continuum limit and Schwinger-Dyson equations.

Findings

Derived Schwinger-Dyson equations match background independent formulations.

Confirmed the continuum limit of the matrix model yields string field theory.

Validated the approach at the multicritical point.

Abstract

Through the continuum limit of the one matrix model on the multicritical point the corresponding Schwinger-Dyson equation of temporal-gauge string field theory is derived. It agrees with that of the background independent formulation recently proposed.
