Talk at 1:30 PM in 511 Lake


 

Abstract: I will discuss how to use Davis complex of a Coxeter group (a CAT(0) piecewise Euclidean complex, on which the group acts properly cocompactly by reflections) to investigate subgroups generated by reflections. In particular, a relation between nerves of a group and its reflection subgroup can be obtained.
 



Here are some directions to Northeastern University. Lake Hall can be best accessed from the entrance on the corner of Greenleaf Street and Leon Street.
