H-measures Applied to Nonhyperbolic Equations

Since their introduction, H-measures have been mostly used in problems related to hyperbolic equations and systems. In this study we give an attempt to apply the H-masure theory to parabolic equations. Through a number of examples we try to present how the differences between parabolicity and hyperbolicity reflect in the theory. We shall try to give some hints how to apply these results to equation that change their type, as the Tricomi equation.
