N1  - Thesis (Ph.D.) - Indian Statistical Institute, 2022; Includes bibliography; Preliminaries -- Tridiagonal kernels and left-invertible operators with applications to Aluthge transforms -- Invariant subspaces of analytic perturbations --  Tridiagonal shifts as compact + isometry -- Left-invertibility of rank-one perturbations; Guided by Prof. Jaydeb Sarkar
N2  - This thesis deals with the merge of a number of operator and function theoretic concepts, namely, reproducing kernels, Aluthge transforms, left invertible operators, compact perturbations of isometries, and invariant subspaces of finite rank perturbations of
isometries. Our study intends to contribute equally to these subjects
