We will talk about some recent results related to the fractional Laplacian $\nabla^s_+=(-\Delta)^{\frac s2} $ and the fractional gradient $\nabla^s_-=\nabla (-\Delta)^{\frac {s-1}{2}}$, including also some optimal inequalities of type Hardy-Rellich/Adams-Moser/Morrey-Sobolev, and regularity of the distributional solutions to the dual equations $[\nabla^s_\pm]^\ast u=f$.

Joint work with Jie Xiao (Memorial University, Canada).
