In previous issues of this MONTHLY, Quadrat, Lasserre, and Hiriat-Urruty [6] generalized the Pythagorean theorem to orthogonal n-simplexes andNash [5], taking a somewhat different approach, derived the n-dimensional version ofthe parallelogram law. In that case all coefficient objects are complexes of sheaves and the pairing that one usually considers is the tensor product of chain complex es.
