The addition of a topologically massive term to an admittedly non-unitarythree-dimensional massive model, be it an electromagnetic system or agravitational one, does not cure its non-unitarity. What about the enlargementof avowedly unitary massive models by way of a topologically massive term? Theelectromagnetic models remain unitary after the topological augmentation but,surprisingly enough, the gravitational ones have their unitarity spoiled. Herewe analyze these issues and present the explanation why unitary massivegravitational models, unlike unitary massive electromagnetic ones, cannotcoexist from the viewpoint of unitarity with topologically massive terms. Wealso discuss the novel features of the three-term effective field models thatare gauge-invariant

IS IT PHYSICALLY SOUND TO ADD A TOPOLOGICALLY MASSIVE TERM TO THREE-DIMENSIONAL MASSIVE ELECTROMAGNETIC OR GRAVITATIONAL MODELS?
