## Abstract An elementary straightforward proof for the boundedness of pseudo β differential operators of the HΓΆrmander class Ξ¨^ΞΌ^~I,Ξ΄~ on weighted Besov β Triebel spaces is given using a discrete characterization of function spaces.
## Abstract We investigate the composition operators on the weighted Hardy spaces __H__^2^(__Ξ²__). For any bounded weight sequence __Ξ²__, we give necessary conditions for those operators to be isometric. The sufficiency of those conditions is wellβknown for the classical space __H__^2^. In the case
