We study Toeplitz operators on Bergman spaces using techniques from the analysis of Dirac-type operators on complete Riemannian manifolds, and prove an index theorem of Boutet de Monvel from this point of view. Our approach is similar to that of Baum and Douglas [2], but we replace boundary value theory for the Dolbeaut operator with much simpler ...

Toeplitz Operators on Dirichlet Spaces
Acta Mathematica Sinica, English Series, 2001Let \(B_n\) be the unit ball in \(\mathbb{C}^n\) and \(\mathcal{D}\) the Dirichlet space, that is, the subspace of analytic functions in the Sobolev space with the norm \[ \left[\sum_{i=1}^n\int_{B_n}\left(\left|\frac{\partial f}{\partial z_i}(z)^2+ \frac{\partial f}{\partial \overline{z_i}}(z)^2 \right|\right) dv\right]^\frac{1}{2}.

Complex Symmetric Toeplitz Operators
Integral Equations and Operator Theory, 2021The paper is devoted to study the complex symmetry for Toeplitz operators, with certain trigonometric symbols, over the Hardy space \(H^2\) of the unit circle \(\mathbb{T}\). A~bounded operator \(T\) on a Hilbert complex space is said to be complex symmetric (respectively, canonically symmetric) operator if there is a conjugation (respectively ...
