Format:

Speakers are invited to give 40 minute talks on the theme of "How do multigradings or nonstandard gradings arise in your work? What do you see as motivating or interesting problems?" The talk is followed by 15 minutes of Q&A. Talks are meant to be loose and free-ranging. Part of the goal is to generate ideas for problems that could be woven into future events, e.g. an AIM workshop, or a working group.
