Critical Collapse in the Axion-Dilaton System in Diverse Dimensions

TL;DR

This paper investigates gravitational collapse in the axion-dilaton system across multiple dimensions, analyzing symmetry effects and calculating critical exponents to understand black hole formation in string theory contexts.

Contribution

It extends previous work by exploring the axion-dilaton collapse in dimensions four through ten and evaluates Choptuik exponents in the elliptic case.

Findings

Choptuik exponents computed for various dimensions

Global SL(2,R) symmetry influences collapse dynamics

Collapse behavior varies with spacetime dimensionality

Abstract

We study the gravitational collapse of the axion-dilaton system suggested by type IIB string theory in dimensions ranging from four to ten. We extend previous analysis concerning the role played by the global SL(2,R) symmetry and we evaluate the Choptuik exponents in the elliptic case.
