What is the fractional Laplacian? A comparative review with new results

A Lischke, G Pang, M Gulian, F Song, C Glusa… - Journal of …, 2020 - Elsevier
The fractional Laplacian in R d, which we write as (− Δ) α/2 with α∈(0, 2), has multiple
equivalent characterizations. Moreover, in bounded domains, boundary conditions must be …
