- Seminar of Probability Group
We will present the recent result of Ramon van Handel (https://arxiv.org/abs/2512.18588) and prove that any 1-subgaussian random vector is dominated in convex ordering by a universal constant times a standard Gaussian vector. This strengthens Talagrand's celebrated subgaussian comparison theorem.
