Buildings, Varieties, and Applications

Buildings are combinatorial objects that model geometric features of groups and their representations. They have numerous connections to algebraic and arithmetic geometry. Algebraic varieties associated to buildings, such as affine Grassmannians, Mustafin varieties and Shimura varieties, offer plenty of untapped potential for computational research and novel applications.

The aim of the meeting is to bring together researchers working in fields related to buildings and algebraic geometry, including those who are relatively unfamiliar with applications of buildings to their work. The program will consist of a number of invited lectures, contributed talks by participants, and unstructured time to build collaborations.

Limited funding is available for participants who will contribute a talk. Further instructions on the talk application follow in the confirmation of registration. The deadline for submission is July 31, 2019.
