    Dilation Theory of Contractions and Nevanlinna-Pick Interpolation Problem 

    Mandal, Samir Ch
    In this article, we give two different proofs of the existence of the minimal isometric dilation of a single contraction. Then using the existence of a unitary dilation of a contraction, we prove the `von Neumann's ...

    Operator Theory on Symmetrized Bidisc and Tetrablock-some Explicit Constructions 

    Sau, Haripada (2018-07-26)
    A pair of commuting bounded operators (S; P ) acting on a Hilbert space, is called a -contraction, if it has the symmetrised bides = f(z1 + z2; z1z2) : jz1j 1; jz2j 1g C2 as a spectral set. For every -contraction (S; P ), ...

    Curvature Calculations Of The Operators In Cowen-Douglas Class 

    Deb, Prahllad (2014-03-03)
    In a foundational paper “Operators Possesing an Open Set of Eigenvalues” written several decades ago, Cowen and Douglas showed that an operator T on a Hilbert space ‘H possessing an open set Ω C of eigenvalues determines ...

    Some Problems in Multivariable Operator Theory 

    Sarkar, Santanu (2017-12-10)
    In this thesis we have investigated two different types of problems in multivariable operator theory. The first one deals with the defect sequence for contractive tuples and maximal con-tractive tuples. These condone deals ...

    Dilations, Functoinal Model And A Complete Unitary Invariant Of A r-contraction. 

    Pal, Sourav (2013-08-02)
    A pair of commuting bounded operators (S, P) for which the set r = {(z 1 +z 2,z 1z 2) : |z 1| ≤1, |z 2| ≤1} C2 is a spectral set, is called a r-contraction in the literature. For a contraction P and a bounded commutant ...

    Curvature Inequalities for Operators in the Cowen-Douglas Class of a Planar Domain 

    Reza, Md. Ramiz (2018-01-04)

    Normal Spectrum of a Subnormal Operator 

    Kumar, Sumit (2018-03-21)
    Let H be a separable Hilbert space over the complex field. The class S := {N|M : N is normal on H and M is an invariant subspace for Ng of subnormal operators. This notion was introduced by Halmos. The minimal normal ...
