Organizers: Suraj Dash and Khai-Hoan Nguyen-Dang
Time: Saturday at 16:00 CEST via Zoom. The first talk will take place on October 2.
The first part of the seminar covers the basic language of Log Geometry based on [OG] Ogus' Lectures on Logarithmic Algebraic Geometry.
Other useful references are [MG] Mark Gross' Tropical Geometry and Mirror Symmetry for more examples and [OL] Martin Olsson's Logarithmic Geometry and Algebraic Stacks for a complement.
