DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/56/">Lo
 calisation of M2-branes and Ensembles</a>\nby Fridrik Freyr Gautason (Univ
 ersity of Southampton) as part of AnLy Strings and Fields online seminars\
 n\n\nAbstract\nI will discuss the M2-brane partition function for a large 
 class of asymptotically locally $AdS_4 \\times S^7$ spacetimes. I will sho
 w how supersymmetry localises the M2-brane position to a fixed point of an
  R-symmetry Killing vector. I will then discuss the one-loop partition fun
 ction of instantonic M2-branes and show that it is assembled out of buildi
 ng blocks familiar to 3D supersymmetric quantum field theories. I will clo
 se out with arguments that M theory on $AdS_4$ is dual to 3D CFT (such as 
 ABJM) in the grand canonical ensemble. In that context the instanton parti
 tion function we obtain is one-loop exact.\n
