Besov and Triebel–Lizorkin space estimates for fractional diffusion

Kôzô Yabuta, Minsuk Yang

Research output: Contribution to journalArticlepeer-review


We study Besov and Triebel–Lizorkin space estimates for fractional diffusion. We measure the smoothing effect of the fractional heat flow in terms of the Besov and Triebel–Lizorkin scale. These estimates have many applications to various partial differential equations.
