Remarks on defective Fano manifolds
arXiv:1702.00625 · doi:10.1007/s11565-017-0270-6
Abstract
This note continues our previous work on special secant defective (specifically, conic connected and local quadratic entry locus) and dual defective manifolds. These are now well understood, except for the prime Fano ones. Here we add a few remarks on this case, completing the results in our papers \cite{LQEL I}, \cite{LQEL II}, \cite{CC}, \cite{HC} and \cite{DD}; see also the recent book \cite{Russo}
