• The Pick-Nevanlinna Interpolation Problem : Complex-analytic Methods in Special Domains 

      Chandel, Vikramjeet Singh (2018-06-13)
      The Pick–Nevanlinna interpolation problem, in its fullest generality, is as follows: Given domains D1, D2 in complex Euclidean spaces, and a set f¹ zi; wiº : 1 i N g D1 D2, where zi are distinct and N 2 š+, N 2, find ...
    • 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 ...
