DESCRIPTION:Speakers: Perseas Christodoulidis (Ewha Womans U)\n\nI will di
 scuss how to construct a gravitational open extension of the effective fie
 ld theory of inflation in the Schwinger-Keldysh framework. While physical 
 symmetries allow many open operators in the Schwinger-Keldysh action\, mos
 t of them overconstrain the equations of motion\, yielding inconsistent dy
 namics. By identifying the minimal open operators compatible with propagat
 ing scalar and tensor modes\, I will construct a local gravitational Schwi
 nger-Keldysh action\, recovering dissipative models of inflation such as w
 arm inflation. I will also briefly discuss how stochastic inflation fits i
 nto this program.\n\nhttps://indico.ibs.re.kr/event/1287/
