The matrix edge of holography
Abstract
The IKKT matrix model arises at the extremal p= -1 limit of holographic dualities based on Dp-brane geometries. We review the one-dimensional maximal supergravity that governs bulk fluctuations dual to the lowest BPS multiplet of gauge-invariant operators in the IKKT model. We present the Killing spinor equations and discuss their general half-supersymmetric solutions within the SO(3)× SO(7)-invariant subsector. The explicit uplift of these solutions to Euclidean IIB supergravity in ten dimensions is provided.
