Geometric invariants for a class of submodules of analytic Hilbert modules
Let $\Omega \subseteq \mathbb C^m$ be a bounded connected open set and $\mathcal H \subseteq \mathcal O(\Omega)$ be an analytic Hilbert module, i.e., the Hilbert space $\mathcal H$ possesses a reproducing kernel $K$, the ... -
Geometrical and Topological Properties of CMB Polarization Fields
Cosmic Microwave Background (CMB) is a relic from the early Universe. It was generated due to the physical processes in the early Universe during an epoch known as the recombination or decoupling epoch. The CMB has highly ... -
Geometry of normed linear spaces in light of Birkhoff-James orthogonality
In this thesis, we have tried to understand the geometry of normed spaces in the light of Birkhoff-James orthogonality. Using the first two chapters to give introductory notes and to establish relevant notations and ... -
Geometry Optimization Of Axially Symmetric Ion Traps
(2009-05-13)This thesis presents numerical optimization of geometries of axially symmetric ion trap mass analyzers. The motivation for this thesis is two fold. First is to demonstrate how the automated scheme can be applied to achieve ... -
Germanosilicate Fibers And Bragg Gratings : Newer Efforts In Understanding Photosensitivity And Novel Methods For Strain-Temperature Discrimination
(2010-12-03)The different topics covered in this thesis include photosensitivity in germanosilicate fibers/glasses and application of fiber Bragg grating sensors in simultaneous strain and temperature discrimination. Fiber Bragg ... -
Glassy Dynamics in Active Matter
There has been much interest in the glassy dynamics of living systems at the scales of subcellular structures, cells and tissues. This has motivated theoretical studies on the approach to glassy behaviour in dense systems ... -
Global gyrokinetic simulations of electrostatic microturbulent transport in LHD stellarator and ADITYA-U tokamak
Tokamak and stellarator are two leading contenders in the quest to achieve nuclear fusion from magnetically-confined plasmas. They differ in terms of magnetic field structure in the toroidal direction. Irrespective of the ... -
Goldman Bracket : Center, Geometric Intersection Number & Length Equivalent Curves
(2017-11-30)Goldman [Gol86] introduced a Lie algebra structure on the free vector space generated by the free homotopy classes of oriented closed curves in any orientable surface F . This Lie bracket is known as the Goldman bracket ... -
Graph Spectral Methods for Analysis of Protein Structures
Network representation of protein structures is an information-rich mode of examining protein structure, dynamics and its interactions with biomolecules. Graph spectral methods are extremely useful and powerful in analysing ... -

(2010-12-08)This thesis presents experimental and related theoretical studies of single layer graphene, bilayer graphene and single walled carbon nanotubes. The thesis is divided into three parts; the first part describes the phonon ... -
Gravitational Waves From Inspiralling Compact Binaries : 3PN Polarisations, Angular Momentum Flux And Applications To Astrophysics And Cosmology
(2010-09-03)Binary systems comprising of compact objects like neutron stars (NS) and/or black holes (BH) lose their energy and angular momentum via gravitational waves (GW). Radiation reaction due to the emission of GW results in a ... -
The Green's Function, the Bergman Kernel and Quadrature Domains in Cn
(2018-06-08)In the first part of this thesis, we prove two density theorems for quadrature domains in Cn ,n≥2. It is shown that quadrature domains are dense in the class of all product domains of the form D×Ωwhere D⊂Cn−1 is a smoothly ... -
