In 1979 Vaaler proved that everyd‐dimensional central section of the cube [−1, 1]nhas volume at least 2d. We prove the following sharp combinatorial analogue. LetKbe ad‐dimensional subspace of ℝn. Then, there exists a probability measurePon the section [−1, 1]n∩Ksuch that the quadratic formdominates the identity onK(in the sense that the difference is positive semi‐definite).
