We discuss both the wave and heat equations as model examples of conservative and irreversible systems respectively and we describe the different tools that have been developed to address these problems.

Some Problems and Results on the Controllability of Partial Differential Equationsresent some recent results on the controllability of the linear system of thermoelasticity which is the simplest one coupling both the hyperbolic and the parabolic nature of the wave and heat equation respectively.

Among the tools I shall discuss are generalized Sobolev inequalities, semi- classical estimates, variational methods, and non-linear elliptic PDE.
