Graduate Seminar on Non-archimedean Geometry Winter 2014/15



Several approaches to non-archimedean geometry


This semester we are organising a seminar on non-archimedean geometry. This is open to master and graduate students or anyone with some background in arithmetic geometry.
We will meet in M006. The first meeting is on Wednesday 8th October 2014 at 8:15, and every Wednesday after that starting at the same time. This may be subject to change which will be posted here.
The goal is to understand the basic ideas, some results and examples of the different approaches to non-archimedean geometry. We will follow closely the lecture notes of Brian Conrad at the Arizona Winter School 2007. Kiran Kedlaya's notes are also recommended.
Each session one person will be responsible to present the main ideas of the section, which should take approximately half of the time. But everyone is encouraged to look at the exercises and examples in the notes beforehand, so that they can be discussed and solved during the rest of meeting. The program can be adjusted depending on the participants. Suggestions are welcome. Especially the last three meetings are not set in stone.
