| Jan 10, 2011 at 9:23 | comment | added | Dmitri Panov | This is a great question, I don't understand why no one apart from me seems to like it :)... To Sasha and Sandor -- it seems to me that you misread the question. The real question start after: "Here is my questions..." , prior to this Mohammad just explains basic things about vanishing cycles, is not he? | |
| Jan 10, 2011 at 6:09 | comment | added | Sasha | In the first part of the question it seems that you just ask for a Lefschetz pencil? I guess if you take a generic pencil of hyperplane sections of $P^4$ in the 5-fold Veronese embedding it is Lefschetz (all singularities of fibers are ODP's). Then you can choose one singular fiber and a small neighborhood of the point of the base of the pencil. | |
