A note on T^5/Z_2 compactification of the M-theory matrix model

TL;DR

This paper investigates the T^5/Z_2 orbifold compactification of the M-theory matrix model, showing how the addition of 16 5-branes is represented within the matrix model framework to ensure consistency.

Contribution

It demonstrates how the addition of 16 5-branes in the T^5/Z_2 compactification is realized in the M-theory matrix model, extending previous understanding of the model's consistency.

Findings

The matrix model accurately reflects the addition of 16 5-branes.

Consistency of the orbifold compactification is maintained in the matrix model.

The study clarifies the role of 5-branes in M-theory compactifications.

Abstract

We study the T^5/Z_2 orbifold compactification of the M-theory matrix model. This model was originally studied by Dasgupta, Mukhi, and Witten. It was found that one had to add 16 5-branes to the system to make the compactification consistent. We demonstrate how this is mimicked in the matrix model.
