First half (joint with Steve Wilson): We describe the connective ku-homology and -cohomology of the Eilenberg-MacLane space K(Z/p,2), using the Adams spectral sequence. There is a nice interplay between exotic and h_0 extensions. Second half (joint with Manyi Guo): The cut locus of a point P on a cube is the set of points Q for which there is more than one shortest path from P to Q. We partition a face of a cube optimally into 193 connected subsets on which the cut locus is constant, up to isomorphism as labeled graphs.
