Abstract
In this paper, we first completely characterize the complex symmetric Toeplitz operators \(T_\varphi \) on the Hardy spaces \(H^2({\mathbb {D}})\) with conjugations \({\mathcal {C}}_p^{i,j}\) and \({\mathcal {C}}_n\). Next, we give a method to determine the coefficients of \(\varphi (z)\) when \(T_\varphi \) is complex symmetric on \(H^2({\mathbb {D}})\) with the conjugation \({\mathcal {C}}_\sigma \), which partially solves a problem raised by [2]. Finally, we consider the complex symmetric Toeplitz operators \(T_\varphi \) on the weighted Bergman spaces \(A^2({\mathbb {B}}_{n})\) and the pluriharmonic Bergman spaces \(b^2({\mathbb {B}}_{n})\) with conjugations \({\mathcal {C}}_V\), where V is a symmetric permutation matrix.
期刊介绍:
Annals of Functional Analysis is published by Birkhäuser on behalf of the Tusi Mathematical Research Group.
Ann. Funct. Anal. is a peer-reviewed electronic journal publishing papers of high standards with deep results, new ideas, profound impact, and significant implications in all areas of functional analysis and all modern related topics (e.g., operator theory). Ann. Funct. Anal. normally publishes original research papers numbering 18 or fewer pages in the journal’s style. Longer papers may be submitted to the Banach Journal of Mathematical Analysis or Advances in Operator Theory.
Ann. Funct. Anal. presents the best paper award yearly. The award in the year n is given to the best paper published in the years n-1 and n-2. The referee committee consists of selected editors of the journal.
