Abstract: Dynamics of eternal inflation on the landscape admits description in terms ofthe Martin-Siggia-Rose MSR effective field theory that is in one-to-onecorrespondence with vacuum dynamics equations. On those sectors of thelandscape, where transport properties of the probability measure for eternalinflation are important, renormalization group fixed points of the MSReffective action determine late time behavior of the probability measure. Iargue that these RG fixed points may be relevant for the solution of the gaugeinvariance problem for eternal inflation.
