We meet every Wednesday, alternatingly in Amsterdam and Leiden. In Amsterdam, we meet 13:30 -- 15:15 (for the remainder of the year: room C616 of the Wis- en Natuurkundegebouw of VU University Amsterdam), and in Leiden it is 14:15 -- 16:00 (usually room 412 of the Snellius building).

Our main reference is L. Szpiro -
