%0 Journal Article %T Spectral Flows and Twisted Topological Theories %A Beatriz Gato-Rivera %A Jose Ignacio Rosado %J Physics %D 1995 %I arXiv %R 10.1016/0370-2693(95)01507-8 %X We analyze the action of the spectral flows on N=2 twisted topological theories. We show that they provide a useful mapping between the two twisted topological theories associated to a given N=2 superconformal theory. This mapping can also be viewed as a topological algebra automorphism. In particular null vectors are mapped into null vectors, considerably simplifying their computation. We give the level 2 results. Finally we discuss the spectral flow mapping in the case of the DDK and KM realizations of the topological algebra. %U http://arxiv.org/abs/hep-th/9504056v2
