This lecture focuses on general structural aspects of open quantum field theories, with particular emphasis on open gauge theories. Topics include: - A systematic algorithm to count physical degrees of freedom in open theories, - Constraints, gauge symmetries, and gauge identities in the advanced and retarded sectors , - The open effective theory of the Nambu–Goldstone boson associated with broken time translations with aplications to inflationary cosmology, - Implications for primordial perturbations and cosmological correlators in the presence of dissipation and noise.
