Function Theory on Tetrablock: Realization, Interpolation, Extension and Toeplitz Corona Theorem

Shubham Jain, Surjit Kumar, Milan Kumar Mal +1

We introduce a Schur-Agler type class associated with the tetrablock and establish a realization theorem for this class. Furthermore, we provide a tetrablock analog of the interpol…

Brown-Halmos type characterization for the tetrablock

Shubham Jain, Surjit Kumar, Milan Kumar Mal +1

In this note, we obtain a Brown-Halmos type characterization for Toeplitz operators on the Hardy space associated with the tetrablock. As an application, we show that the zero oper…

Cartan Isometries and Toeplitz Operators on Cartan domains

Surjit Kumar, Milan Kumar Mal, Paramita Pramanick

We provide a description of the Shilov boundary of the classical Cartan domain in terms of Jordan triple determinant. As a consequence, we obtained an intrinsic characterization of…
