TOPOLOGICAL MASSIVE SIGMA-MODELS

In this paper we construct topological sigma models which include a po tential and are related to twisted massive supersymmetric sigma models . Contrary to a previous construction these models have no central cha rge and do not require the manifold to admit a Killing vector. We use the topological massive sigma model constructed here to simplify the c alculation of the observables. Lastly it is noted that this model can be viewed as interpolating between topological massless sigma models a nd topological Landau-Ginzburg models.
