The simplicial approach to buildings

Student-Run Algebraic Geometry Seminar

Speaker: Christopher Westenberger, UC Davis
Location: 2112 MSB
Start time: Thu, Dec 1 2011, 3:10PM

Buildings will be introduced not as places to hold seminars in, but rather as simplicial complexes which can be expressed as a union of subcomplexes (called apartments) subject to additional axioms. I will introduce several examples of buildings and if time permits the homotopy type of a building will be discussed.
