Optimal weighted Poincaré inequalities for the Barenblatt and uniform densities in $$\mathbb R^n$$

Year: 2026
Type: article
Abstract: We prove weighted n -dimensional Poincaré inequalities for Barenblatt densities, which are stationary states of certain Fokker–Planck type equations with non-constant diffusion coefficients. The interest in Poincaré inequalities for Barenblatt densities stems from their deep connection with the trend-to-equilibrium problem for Fokker–Planck type equations that admit these densities as steady states.
