The optimal symmetric quasi-Banach range of the discrete Hilbert transform

Abstract

We identify the symmetric quasi-Banach range of the discrete Calderón operator and Hilbert transform acting on a symmetric quasi-Banach sequence space. As an application, we present an example of the optimal range in the case when the domain of those operators is the weak-\(\ell _{1}\) space of sequences.

Acknowledgements

I would like to thank Professor F. Sukochev for bringing this problem to my attention and for the support of the one year visit to the School of Mathematics and Statistics, UNSW, and the warm atmosphere at the department, where a preliminary version of the paper was written. I would also like to thank Dr. D. Zanin for his very useful comments and helps which led to many corrections and improvements. I thank the anonymous referee for reading the paper carefully and providing thoughtful comments, which improved the exposition of the paper. This work was partially supported by the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan.
