Homogeneous Calderón–Zygmund estimates for a class of second-order elliptic operators

G. P. Galdi; Giorgio Metafune; Chiara Spina; C. Tacelli

We prove unique solvability and corresponding homogeneous Lp estimates for the Poisson problem associated to the uniformly elliptic operator , provided the coefficients are bounded and uniformly continuous, and admit a (non-zero) limit as |x| goes to infinity. Some important consequences are also derived.

Lp–Lq estimates for homogeneous operators

Norisuke Ioku; Giorgio Metafune; Motohiro Sobajima; Chiara Spina

We prove precise Lp–Lq estimates for the semigroup generated by L = |x|αΔ + c|x|α−1 x |x|⋅∇− b|x|α−2 in Lp(ℝN).
