We pro ve the Kuznetsov components of a series of hypersurface in projective spac e reconstruct the hypersurfaces. Our method allow us to work for hypersurf aces in weighted projective space\, and prove the reconstruction theorem f or veronese double cone\, which is a long-time open case. Joint with J. Re nnemo and Shizhuo Zhang. In the second part\, I will talk about the infini tesimal categorical torelli for Fano 3-folds. I will prove the classical infinitesimal torelli for Fano 3-folds using the infinitesimal categorical torelli\, especially for special Gushel-Mukai 3-folds. Joint with Shizhuo Zhang and Zheng Zhang.\n LOCATION:https://researchseminars.org/talk/HKUST-AG/82/ END:VEVENT END:VCALENDAR
