 nTitle: Open EFTs for Cosmology\nSpeaker: Perseas Christodoulidis\nAbstrac
 t: \nI will discuss how to construct a gravitational open extension of th
 e effective field theory of inflation in the Schwinger-Keldysh framework. 
 While physical symmetries allow many open operators in the Schwinger-Keldy
 sh action\, most of them overconstrain the equations of motion\, yielding 
 inconsistent dynamics. By identifying the minimal open operators compatibl
 e with propagating scalar and tensor modes\, I will construct a local grav
 itational  Schwinger-Keldysh  action\, recovering dissipative models of 
 inflation such as warm inflation. I will also briefly discuss how stochast
 ic inflation fits into this program.\n\nhttps://indico.kias.re.kr/event/40
