17-21 August 2026
Inspired by the long-standing annual US Automorphic Forms Workshop, this workshop aims to generate and sustain a friendly and supportive atmosphere that provides encouragement to young researchers, mentoring opportunities for more established researchers, as well as a lively forum for exchanging ideas and forming new collaborations. All workshop participants are encouraged to speak on their research. There are no guest speakers, but the time is shared equally between all speakers. The workshop will also feature at least one panel discussion on a topic of interest to the participants.
