Hardy spaces and Campanato spaces associated with Laguerre expansions and higher order Riesz transforms
The Anh Bui, Xuan Thinh Duong
Let \(\mathcal{L}_ν\) be the Laguerre differential operator which is the self-adjoint extension of the differential operator \[ L_ν:= \sum_{i=1}^n \left[-\frac{\partial^2}{\partial…
