Polychromatic edge-colorings of the hypercube (Part I)

A p-coloring of the edges of the n-dimensional hypercube graph Q_n is called d-polychromatic if all p colors are used in all the d-dimensional subcubes of Q_n. For example all edges receiving the same color defines a polychromatic coloring in 1 color. Naturally, we are interested in using as many colors as possible in a polychromatic coloring.

This problem was raised in a joint paper with Noga Alon and Anja Krech (in relation to Turan-type problems within the hypercube) and was solved recently by David Offner who is a graduate student at Carnegie Mellon University. In the talk we hope to fully explain his solution.
