The linear stability of a two-fluid interface forced by a shear flow, or of a floating elastic sheet under confinement, is characterized by an eigenvalue problem. In the first case, the problem is dynamic and of second order. In the other case, it is static and of fourth order. I will show how asymptotic methods provide a physical insight on the various solutions of both problems, and subsequently on the phenomenology of waves and wrinkles.
