| Dec 22, 2021 at 3:10 | comment | added | Jason Starr | When $Y$ is the projective line and $X$ and $D$ are both Fano manifolds, the Cohen-Jones-Segal conjecture predicts a Lefschetz property: the usual Lefschetz property for $D$ inside $X$ implies a Lefschetz property for the double loop spaces, and then you apply Cohen-Jones-Segal. Please feel free to e-mail me for more details (I lectured about this a couple of times recently). | |
