Studying linear systems of wave equations on a fixed background geometry is often a first step towards understanding the non-linear setting. The talk describes a theory for linear systems of wave equations on a class of cosmological backgrounds. The main result of the theory is optimal energy estimates. However, it also gives conclusions concerning the asymptotics of solutions, sometimes even a homeomorphism between initial data and asymptotic data.

This talk is part of the Partial Differential Equations seminar series.
