Observational Aspects Of Core Collapse Supernovae
(20131017)The discovery of several bright supernovae (SNe) in recent years has evoked a great deal of interest in these objects. The study of these objects are of importance not only as probes to the end stages of stellar evolution, ... 
Observational Constraints on Global 21cm Signal from the Epoch of Reionization
One of the most promising probes of Cosmic Dawn (CD) and Epoch of Reionization (EoR) is the restframe global 21cm signal of neutral hydrogen (HI) produced by the intergalactic medium (IGM) prior to the end of the EoR ... 
Observational study of CoreCollapse Supernovae
The advent of dedicated surveys for studying transient events has invoked a great interest in the study of supernovae (SNe). The rate of discovery of SNe has hence gone up tenfold relinquishing their diversity. SNe not ... 
On an ODE Associated to the Ricci Flow
(20180418)We discuss two topics in this talk. First we study compact Ricciflat four dimensional manifolds without boundary and obtain point wise restrictions on curvature( not involving global quantities such as volume and diameter) ... 
On Critical Points of Random Polynomials and Spectrum of Certain Products of Random Matrices
(20180730)In the first part of this thesis, we study critical points of random polynomials. We choose two deterministic sequences of complex numbers, whose empirical measures converge to the same probability measure in complex plane. ... 
On The Analytic Theory Of Explosions
(20120531) 
On the electrical transport of weak topological insulators and Weyl semimetals
Topological insulators have garnered enormous amount of attention owing to their unique topological properties. The surface states protected by the topology of the system hold limitless potentials including topological ... 
On the Geometry and Operator Theory of the Bidisc and the Symmetrized Bidisc
This work is concerned with the geometric and operator theoretic aspects of the bidisc and the symmetrized bidisc. First we have focused on the geometry of these two do mains. The symmetrized bidisc, a nonhomogeneous ... 
On the Kobayashi geometry of domains
In this thesis we study questions broadly related to the Kobayashi (pseudo)distance and (pseudo)metric on domains in ℂn. Specifically, we study the following subjects: Estimates for holomorphic images of subsets in convex ... 
On The Magnetic And Magnetotransport Studies Of Cobaltates And Superconductor/ Ferromagnet Heterostructures
(20110630)The study of the coexistence of singlet superconductivity and ferromagnetism in bulk materials has been a long standing and intriguing problem in condensed matter physics since the superconductivity and ferromagnetism are ... 
On the Nature Of Propagating MHD Waves In The Solar Atmosphere
(20141015)One of the most persistent problem in solar physics is the identification of the mechanism that heats the solar corona and accelerates the fast solar wind. Magnetohydrodynamic (MHD)waves play a crucial role in heating of ... 
On The PeakToAveragePowerRatio Of Affine Linear Codes
(20080125)Employing an error control code is one of the techniques to reduce the PeaktoAverage Power Ratio (PAPR) in an Orthogonal Frequency Division Multiplexing system; a well known class of such codes being the cosets of ... 
On the Stability of Certain Riemannian Functionals
(20180306)Given a compact smooth manifold Mn without boundary and n ≥ 3, the Lpnorm of the curvature tensor, defines a Riemannian functional on the space of Riemannian metrics with unit volume M1. Consider ... 
On The Structure of Proper Holomorphic Mappings
(20170928)The aim of this dissertation is to give explicit descriptions of the set of proper holomorphic mappings between two complex manifolds with reasonable restrictions on the domain and target spaces. Without any restrictions, ... 
Onboard Failure Diagnostics and Failure Prediction of High Power White Light Emitting Diodes Used in Safety Critical Applications
Light Emitting Diodes (LEDs) have become a focus of global lighting community owing to their long service life, low energy consumption and environmental friendliness. The everincreasing use of LEDs in many applications ... 
One Dimensional Transport And Prospects Of Structural Transitions In Ultrathin Metallic Wires
(20130225)This thesis reports transport in ultrathin single crystalline nanowires of gold (∼ 2nm). These nanowires were fabricated using an oriented attachment process whereby nanoparticles of appropriate dimensions join in a linear ... 
Operator Theory on Symmetrized Bidisc and Tetrablocksome Explicit Constructions
(20180726)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 ), ... 
Optical And Structural Investigations Of Defects In CdZnTe(Zn ~ 4%) Crystals
(20130612)The CdTe family members (in particular CdZnTe) remain the substrate of choice for epitaxial growth of HgCdTe for use in high performance infrared (IR) detectors and focal plane arrays. This is the case despite advances in ...
