DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HETatNTUA/4/
 ">Holography in 2d N=(0\,4) quantum field theory</a>\nby Kostas Filippas (
 Swansea University) as part of High Energy Theory\, Gravity  and Cosmology
  Seminars @ NTUA\n\n\nAbstract\nWe explore the duality between AdS3 massiv
 e IIA string theory vacua and two-dimensional N=(0\,4) quiver quantum fiel
 d theories. After categorizing all kinds of gravity solutions\, we demysti
 fy the ones that seem to reflect anomalous dual gauge theories. In particu
 lar\, we prove that there are bound states of D-branes on the boundary of 
 the space which provide the dual quiver theory with exactly the correct am
 ount of matter in order to cancel its gauge anomalies. Then we propose tha
 t the structure of the field theory should be complemented with additional
  bifundamental matter\, which we argue it may only be N=(4\,4) hypermultip
 lets. Finally\, we construct a BPS string configuration and use the old an
 d new supersymmetric matter to build its dual ultraviolet operator.\n
