Abstract.- I will discuss the problem of studying long-time behaviour of small-amplitude solutions for multidimensional wave equations (like NLS and nonlinear Klein-Gordon), and will present a KAM-theory which describes behaviour of such solutions for the space-multidimensional beam equation in any space dimension. This is a joint work with H.Eliasson and B.Grebert.
