Some Remarks on the Riesz and reverse Riesz transforms on Broken Line
Dangyang He
In this note, we study both the Riesz and reverse Riesz transforms on broken line. This model can be described by equipped with the measure $dμ= |r|…

Reverse Riesz Inequality on Manifolds with Ends
Dangyang He
In our investigation, we focus on the reverse Riesz transform within the framework of manifolds with ends. Such manifolds can be described as the connected sum of finite number of…

Endpoint Estimates For Riesz Transform And Hardy-Hilbert Type Inequalities
Dangyang He
We consider a class of non-doubling manifolds defined by taking connected sum of finite Riemannian manifolds with dimension N which has the form $\mathbb{R}^{n_i}\tim…
