    In spite of being maximally symmetric, quantum field theory in de Sitter space requires to reconsider a number of concepts familiar in flat space, such as regularisation, analyticity etc. I will describe some of them by considering cosmological correlation functions at 1-and 2-loop level.

    Functional renormalisation group (RG) flows have been used since 50 years for the resolution of quantum field theories (QFT) in terms of their generating functionals such as the partition function, the Wilsonian effective action or the one-particle irreducible effective action. From early on, generalised functional RG flows have been devised that do not only accommodate the stepwise...
