I plan to have all our CAGS talks conducted a hybrid fashion; in person and on Zoom. Some CAGS talks, international talks for example, will only be virtual on Zoom. All talks will be given 12:30 -- 1:30 PM on Fridays in our Seminar room Exploratory Hall, room 4106 unless otherwise stated. The room is equipped with white boards, and a projector. -- If you like to participate please send me, your devoted CAGS Chair, an email and I will try my best to schedule your talk. If you prefer to give a Zoom talk then I will send you a Zoom invitation.
CAGS Chair: Geir Agnarsson
The CAGS is intended as an informal venue, where faculty members, graduate students, visitors from near and far can come and give informal talks on their research, interesting new topics, open problems or just share their thoughts/ideas on anything interesting relating to combinatorics, algebra and discrete geometry. Needless to say, all are welcome to attend, and those who want to give a talk, should email me Geir ("gagnarss followed by the at sign gmu dot edu") the title and a short abstract. The talks should be no longer than 50 minutes long; leaving a few minutes for questions, comments and further discussions afterwards.
