We consider the initial value Cauchy problem for a class of evolutionequations whose Hamiltonian is the Weyl quantization of a homogeneous quadraticform with non-negative definite real part. The solution semigroup is shown tobe strongly continuous on several spaces: the Shubin--Sobolev spaces, theSchwartz space, the tempered distributions, the equal index Beurling typeGelfand--Shilov spaces and their dual ultradistribution spaces.
