The main two families of real hypersurfaces in complex space forms are Hopf and ruled. However, very little is known about the indefinite projective \({\mathbb {C}}P^n_p\). In a previous work, Kimura second author introduced this paper, ruled introduced, as those whose maximal holomorphic distribution integrable, such that leaves totally geodesic hyperplanes. A detailed description shape operat...

We describe a construction of fuzzy spaces which approximate projective toric varieties. The construction uses the canonical embedding of such varieties into a complex projective space: The algebra of fuzzy functions on a toric variety is obtained by a restriction of the fuzzy algebra of functions on the complex projective space appearing in the embedding. We give several explicit examples for ...
