BIRS Workshop on Quasisymmetric Functions.

Every day breakfast will be served from 7:00am-9:00am, lunch will be served at 12:30pm-1:30pm, and dinner will be at 6:30pm-7:30pm. All meals will be served buffet style in the Sally Borden Building. Coffee will be served in Corbett Hall at 10:25-10:45am and from 2:30-3:00 before the afternoon session. There will be a break from 4:25-4:45 but there won't be coffee service for that break. Note, we have one evening session on Tuesday.
