SUMMARY:The Path Integral for Volume-Weighted Eternal Inflation - Steven G
 ratton (IoA)

CONTACT:Antony Lewis
DESCRIPTION:In this talk I present a path integral formulation of slow-rol
 l\nstochastic inflation that can be naturally extended to incorporate\nvol
 ume-weighting effects.  We can gain much insight into what happens in\nete
 rnal inflation by looking for saddle points of the path integral ---\nperh
 aps surprisingly\, some of the saddle points turn out to be complex! \nThu
 s we can investigate the end of eternal inflation (i.e. the\n"youngness pa
 radox") and the (in-)sensitivity of eternal inflation to\ninitial conditio
 ns.
