DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Kadanoff/12/
 ">Dispersion relations for S-matrices and CFTs</a>\nby Simon Caron-Huot (M
 cGill) as part of Kadanoff seminars\n\n\nAbstract\nDispersion relations ar
 e statements of causality.  They give sum rules connecting low and high en
 ergies.  They are great.  I will review some recently derived consequences
  of causality and how they relate to dispersion relations. I will then dis
 cuss a surprising equivalence between three seemingly distinct dispersion 
 relations in CFTs (in position space\, Mellin space\, and analytic functio
 nals)\, and a lesson for flat-space gravity.\n
