Abstract
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.
Speaker Intro
Hu chuangqiang joined Bimsa in the autumn of 2021. The main research fields include: coding theory, function field and number theory, singularity theory. In recent years, he has made a series of academic achievements in the research of quantum codes, algebraic geometric codes, Drinfeld modules, elliptic singular points, Yau Lie algebras and other studies. He has published 13 papers in famous academic journals such as IEEE Trans. on IT., Final Fields and their Applications, Designs, Codes and Cryptography. He has been invited to attend domestic and international academic conferences for many times and made conference reports.
