Abstract
We study the behaviour of linear partial differential operators with polynomial coefficients via a Wigner type transform. In particular, we obtain some results of regularity in the Schwartz space SS and in the space SωSω as introduced by Björck for weight functions ω. Several examples are discussed in this new setting.
