"A supergravity dual for IKKT holography" by Henning Samtleben (ENS Lyon)
A particularly interesting corner of the holographic dualities is the correspondence between the backgrounds of Dp-branes and their non-conformal field theory duals. Extrapolating this correspondence to the extremal case of p=-1, suggests a holographic duality for the IKKT matrix model. The dual D-instanton background is a half-supersymmetric BPS solution of Euclidean IIB supergravity. I describe the relevant maximally supersymmetric one-dimensional supergravity theory around this background and the match of its fields to the lowest BPS multiplet of gauge invariant operators of the IKKT model.
