String Dualities from Matrix Theory: A Summary

TL;DR

This paper reviews how Matrix theory reveals the $SL(5,Z)$ U-duality group of M-theory on $T^4$ and the geometric duality between M-theory on K3 and the Heterotic string on $T^3$, highlighting their manifest nature.

Contribution

It summarizes the realization of U-duality groups and dualities in Matrix theory, emphasizing their geometric and explicit representation.

Findings

Matrix theory exhibits the $SL(5,Z)$ U-duality group for M-theory on $T^4

Duality between M-theory on K3 and Heterotic string on $T^3$ is geometrical and manifest

Dualities are explicitly realized within the Matrix theory framework

Abstract

I review the appearance, within Matrix theory, of the $SL(5,Z)$ U-duality group of M-theory on $T^4$, and the duality between M-theory on K3 and the Heterotic string on $T^3$. In both cases the duality is geometrical and manifest.
