title = "Dimension-free L2 maximal inequality for spherical means in the hypercube",
abstract = "We establish the maximal inequality claimed in the title. In combinatorial terms this has the implication that for sufficiently small ε > 0, for all n, any marking of an e fraction of the vertices of the n-dimensional hypercube necessarily leaves a vertex x such that marked vertices are a minority of every sphere centered at x.",
