IIB matrix model and regularized big bang

TL;DR

This paper explores how the large-N master field of the Lorentzian IIB matrix model can produce a degenerate metric resembling a regularized big bang, linking it to the model's fundamental length scale.

Contribution

It demonstrates a connection between the IIB matrix model's master field and a degenerate metric that models a regularized big bang scenario.

Findings

Derivation of the degenerate metric from the master field.

Calculation of the length parameter in terms of the model's scale.

Insight into the geometric implications of the IIB matrix model.

Abstract

The large-$N$ master field of the Lorentzian IIB matrix model can, in principle, give rise to a particular degenerate metric relevant to a regularized big bang. The length parameter of this degenerate metric is then calculated in terms of the IIB-matrix-model length scale.
