Abstract

We establish the conditions for the induced generalized metric F structure of an oriented hypersurface of a generalized K\"ahler manifold to be a generalized CRFK structure. Then, we discuss a notion of generalized almost contact structure on a manifold MM that is suggested by the induced structure of a hypersurface. Such a structure has an associated generalized almost complex structure on M×\mathdsRM\times\mathds{R}. If the latter is integrable, the former is normal and we give the corresponding characterization. If the structure on M×\mathdsRM\times\mathds{R} is generalized K\"ahler, the structure on MM is said to be binormal. We characterize binormality and give an example of binormal structure.
