The emergence of noncommutative target space in noncritical string theory

TL;DR

This paper demonstrates how noncommutative phase space naturally arises in noncritical string theory, with the string coupling acting as the deformation parameter, revealing a novel geometric structure in the theory.

Contribution

It introduces the emergence of noncommutative geometry in noncritical string theory and identifies the string coupling as the deformation parameter.

Findings

Noncommutative phase space appears naturally in noncritical string theory.

The deformation parameter is identified as the string coupling.

Provides a new geometric perspective on string interactions.

Abstract

We show how a noncommutative phase space appears in a natural way in noncritical string theory, the noncommutative deformation parameter being the string coupling.
