The sharp one-dimensional convex sub-Gaussian comparison constant

Damek Davis, Sam Power

Let $X$ be an integrable real random variable with mean zero and two-sided sub-Gaussian tail $P (∣ X ∣ > t) \leq 2 e^{- t^{2} /2}$ for all $t \geq 0$ . We determine the smallest consta…

Counting partial Hadamard matrices in the cubic regime

Damek Davis

We give a precise asymptotic formula for the number of $n \times 4 t$ partial Hadamard matrices in the regimes $t / n^{3} \to \infty$ and $t / n^{3} \to Θ$ for sufficiently large fixed $Θ$ . This…
