SUMMARY:Fabian Hahner (WU) - 
DESCRIPTION:Speaker: Fabian Hahner (WU)\n\nTitle: The IKKT Matrix Model and
  Twisted Holography\n\nAbstract:\nTwisted holography isolates protected su
 bsectors of holographic dualities\, where both sides can be described exac
 tly. In this talk I will explore this idea for the IKKT matrix model\, the
  dimensional reduction of ten-dimensional super Yang–Mills theory to a p
 oint. I will first explain how supersymmetric theories are formulated in t
 he BV formalism and how twisting by a square-zero supercharge produces a s
 impler\, topological-holomorphic theory that captures protected quantities
 . I will then work out the minimal twist of the IKKT model in detail and c
 ompare it with BCOV theory arising as the holomorphic twist of type IIB su
 pergravity. Finally\, I will discuss work in progress on the other twists 
 of the matrix model\, some of which only appear in the limit of infinitely
  many D-instantons.\n\n&nbsp\;\n\nChange of schedule and room:\n\nRoom: 1.
