There will be a Summer School in Infinite Matroid Theory from the 19th to 25th of July at the youth hostel in Bosau, near Hamburg, Germany. More details are available at http://www.math.uni-hamburg.de/home/bowler/im15
It is aimed at doctoral students and other young researchers, especially graph theorists, who are already familiar with the basic theory of finite matroids. The aim is to give the participants a sufficient grounding in the theory of infinite matroids that they can start to work independently in the field. The organisers are Nathan Bowler and Johannes Carmesin.
There are no accommodation costs, and we have a little money to help pay for travel in exceptional cases. If you have any questions, feel free to email us at im15@math.uni-hamburg.de
