Abstract: Top down holography relies on a decoupling limit of closed and open strings near the horizon of a stack of D branes. The simplest such horizon geometries are of the form of an AdS space times a sphere times a torus with the total product space being a 10 or 11-dimensional solution of supergravity. I will explain that this picture naturally leads one to consider an extreme case which would be AdS1 x S1 x T9 and it would originate from a brane bound state given by the so-called D7 -D instanton system, which is not fully understood in supergravity. I will point out that the dual matrix model seems already written down in the literature before and it is an extension of the IKKT matrix model. I will attempt to be pedagogical and the talk will mostly reflect the supergravity side of the problem.
