Causality and Renormalization in Finite-Time-Path --- Out-of-Equilibrium $phi^3$ QFT

We use the retarded/advanced basis of out-of-equilibrium Green functions. We use the dimensional regularization method and find the correspondence of diverging contributions in the Feynman diagrams and their counterparts in R/A basis.
