DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EASW/25/">QF
 T\, EFT and GFT</a>\nby Aninda Sinha (Indian Institute of Science) as part
  of East Asian String Webinars\n\n\nAbstract\nI will talk about an intrigu
 ing correspondence between 2-2 scattering in quantum field theory (QFT) an
 d an area of mathematics called geometric function theory (GFT). The area 
 of GFT that we will focus on is the theory of typically real\, univalent f
 unctions which are the relevant objects to understand scattering amplitude
 s. This understanding relies heavily on a crossing symmetric dispersion re
 lation for 2-2 scattering that was recently resurrected and furthered in t
 he context of effective field theories (EFT). Time permitting\, I will exp
 lain how to get the crossing symmetric EFT-hedron in effective field theor
 ies.\n
