Vladimir Baranovsky (UC Irvine), Integral model for graph configuration spaces
ZoomThis is a report on the joint work with Matthew Levy. We use surjection operations on integral cochains tof a topological space X (described by McClure-Smith and Berger-Fresse) to describe a complex computing (co)homology of the cartesian power of X with some diagonals removed.
