Log geometry seminar Leiden Fall 2020

Description

This seminar aims to introduce the basic definitions and concepts of log geometry, with log curves being of special interest, and use this theory to give a modular description of log blowups of the moduli space of curves. If you are interested in giving a talk related to this subject in this seminar, please contact Pim.

The seminar will be held on Wednesdays, from 14:00 to 15:00. The first installment will be on the 30th of September. Please contact Pim to be added to the mailing list. This seminar will be online; a zoom link will be sent to everyone on the mailing list.
