Inner and characteristic functions in polydiscs

Ramlal Debnath, Deepak K. Pradhan, Jaydeb Sarkar

Characteristic functions of linear operators are analytic functions that serve as complete unitary invariants. Such functions, as long as they are built in a natural and canonical…

Pairs of inner projections and two applications

Ramlal Debnath, Deepak K. Pradhan, Jaydeb Sarkar

Orthogonal projections onto closed subspaces of of the form for inner functions on are referred to as inner projections,…

Characterizations of complex symmetric Toeplitz operators

Sudip Ranjan Bhuia, Deepak Pradhan, Jaydeb Sarkar

We present complete characterizations of Toeplitz operators that are complex symmetric. This follows as a by-product of characterizations of conjugations on Hilbert spaces. Notably…

Partially isometric Toeplitz operators on the polydisc

Deepak K. D, Deepak Pradhan, Jaydeb Sarkar

A Toeplitz operator , , is a partial isometry if and only if there exist inner functions such that and…

Submodules in polydomains and noncommutative varieties

Susmita Das, Deepak Kumar Pradhan, Jaydeb Sarkar

Tensor product of Fock spaces is analogous to the Hardy space over the unit polydisc. This plays an important role in the development of noncommutative operator theory and function…

Commutant lifting and Nevanlinna-Pick interpolation in several variables

Deepak K. D., Deepak Pradhan, Jaydeb Sarkar +1

This paper concerns a commutant lifting theorem and a Nevanlinna-Pick type interpolation result in the setting of multipliers from vector-valued Drury-Arveson space to a large clas…
