Streszczenie
We are interested in Gaussian versions of the classical Brunn–Minkowski inequality. We prove in a streamlined way a semigroup version of the Ehrhard inequality for $m$ Borel or convex sets based on a previous work by Borell. Our method also yields semigroup proofs of the geometric Brascamp–Lieb inequality and of its reverse form, which follow exactly the same lines.
