The Geometry of Real Anisotropic Bohnenblust--Hille Constants
Abstract
We determine the growth scale of the optimal constants in the real anisotropic Bohnenblust--Hille inequality. For an exponent vector q(m), write Cq(m)(m) for its optimal constant and dm for its diameter. These constants are superpolynomial precisely when m dm/log m→∞; throughout this regime, their logarithm has the sharp scale m dm. If also dm→0, then log Cq(m)(m)/(m dm) lies asymptotically in the interval [(log 2)/4,(2−log 2−γ)/4], where γ is the Euler--Mascheroni constant; this interval has width less than 10−2. We also solve the extremal problems at fixed diameter and fixed total deficit. The normalized reciprocal-deficit profiles order the canonically arranged optimal constants by majorization, yield exact formulas on a full-dimensional region, and recover the lower coefficient (log 2)/4 throughout a broad class of anisotropic regimes.

AB - We determine the growth scale of the optimal constants in the real anisotropic Bohnenblust--Hille inequality. For an exponent vector q^(m), write C_q^(m)^(m) for its optimal constant and d_m for its diameter. These constants are superpolynomial precisely when m d_m/log m→∞; throughout this regime, their logarithm has the sharp scale m d_m. If also d_m→0, then log C_q^(m)^(m)/(m d_m) lies asymptotically in the interval [(log 2)/4,(2−log 2−γ)/4], where γ is the Euler--Mascheroni constant; this interval has width less than 10^−2. We also solve the extremal problems at fixed diameter and fixed total deficit. The normalized reciprocal-deficit profiles order the canonically arranged optimal constants by majorization, yield exact formulas on a full-dimensional region, and recover the lower coefficient (log 2)/4 throughout a broad class of anisotropic regimes.
