Abstract

The IKKT matrix model arises at the extremal p=1p= -1 limit of holographic dualities based on Dpp-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)\rm{SO}(3)\times \rm{SO}(7)-invariant subsector. The explicit uplift of these solutions to Euclidean IIB supergravity in ten dimensions is provided.
