Description
Yang–Mills matrix models are simple yet rich laboratories for studying emergent geometry and holography. Some of them, such as IKKT and polarised IKKT, are proposed matrix descriptions of type IIB string theory. In this talk, I will focus on mass-deformed Yang–Mills matrix models in the strong ’t Hooft coupling limit, where a dual supergravity description may be expected. The central question is whether the matrices effectively commute in this regime, so that their eigenvalues can be interpreted as target-space coordinates. We will see that the answer depends sharply on the number of fermionic degrees of freedom.
