Fractional Poincaré inequalities for general measures

Good-λ inequalities, Calder´ on-Zygmund decomposition, Muckenhoupt weights, vector-valued inequalities, extrapolation, singular non-integral operators, commutators with bounded

Therefore it is reasonable to expect that the Ornstein–Uhlenbeck semigroup may satisfy some form of L p (γ)–L q (γ) off-diagonal estimates if we restrict the testing sets E, F

We describe the Martin compactification for a class of subelliptic operators on S and give sharp pointwise estimates for the corresponding Poisson kernel on

Andrews shows that convex surfaces moving by Gauss curvature converge to round points without any initial pinching condition.. For general speeds of higher

So it is a natural idea to consider Kol- mogorov kernel estimates replacing the Gaussian semigroup by the Kolmogorov semigroup ( T ( t )) t ≥ 0 , thus getting a majorising

The aim of this paper is to find estimates of the Green’s function of stationary discrete shock profiles and discrete boundary layers of the modified Lax–Friedrichs numerical scheme,

Motivated by recent work of Au, C´ ebron, Dahlqvist, Gabriel, and Male, we study regularity properties of the distribution of a sum of two selfad- joint random variables in a

Conversely, it is easy to check that the latter condition implies that T a is bounded.. Moreover Λ is composed of eigenvalues λ associated with finite dimensional vector
