The strong log-concavity for first eigenfunction of the Ornstein-Uhlenbeck operator in the class of convex bodies
Lei Qin
In this paper, we prove that the first (positive) Dirichlet eigenvalue of the Ornstein-Uhlenbeck operator \[ L(u)=Δu-(\nabla u,x), \] is strongly log-concave if the domain is bound…
