DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CCTP_HEP/3/"
 >The connection problem for AdS2</a>\nby Achilleas Porfyriadis (Harvard Un
 iversity) as part of CCTP HEP Seminars\n\n\nAbstract\nI will talk about th
 e problem of extending anti-de Sitter solutions away from the near-horizon
  region of (near-)extreme black holes and connecting them with solutions i
 n the black holes far asymptotically flat region. In Part I of the talk I 
 will present analytic solutions to the connection problem for coupled grav
 itational and electromagnetic perturbations of AdS2xS2 and near-AdS2xS2 in
  the extreme and near-extreme Reissner-Nordstrom black holes\, respectivel
 y. In Part II of the talk I will discuss a calculation of backreaction in 
 AdS2. In this calculation\, an AdS2xS2 throat geometry reacts to a perturb
 ation by a scalar field in such a way that\, with leaky boundary condition
 s\, it maintains its connection to the far asymptotically flat region of t
 he black hole.\n
