Abstract
A boundary value problem related to a parabolic higher order op-erator with a small parameter "e" is analized. For "e "tends to zero, the reduced operator is hyperbolic. When t tends to infinity and "e " tends to zero a parabolic hyperbolic boundary layer appears. In this paper a rigorous asymp-totic approximation uniformly valid for ali t is establishedFile in questo prodotto:
