摘要

This talk reviews the recent work of Philipp Licht, INFINITESIMAL TORELLI FOR WEIGHTED COMPLETE INTERSECTIONS AND CERTAIN FANO THREEFOLDS. This paper generalizes the classical approach of describing the infinitesimal Torelli map in terms of multiplication in a Jacobi ring to the case of quasi-smooth complete intersections in weighted projective space. The results of this talk are used to prove Lang-Vojta’s conjecture for the moduli of such Fano threefolds. We end the talk with an open discussion on the generalization of these results.
