Abstract : The report describes research involving passive evolution equations where, for example, it is shown that passitivity, positivity of the resolvent, and maximal dissipativeness are all equivalent. Further, some classical theorems of HilleYosida and Phillips concerning contraction semigroups are strengthened, where results obtained tie together some of the classical theory of semigroups with that of passive systems.
