Simplicial Complexes, Configuration Spaces, and “Chromatic” Invariants (Andrew Cooper, NC State)
Roberts North 104, CMC 320 E. 9th St., Claremont, CA, United StatesGiven a space $X$, the configuration space $F(X,n)$ is the space of possible ways to place $n$ points on $X$, so that no two occupy the same position. But what if we allow some of the points to coincide? The natural way to encode the allowed coincidences is as a simplicial complex $S$. I will […]
