Normal Spectrum of a Subnormal Operator
(20180321)Let H be a separable Hilbert space over the complex field. The class S := {NM : 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 ... 
Novel Upwind and Central Schemes for Various Hyperbolic Systems
(20180521)The class of hyperbolic conservation laws model the phenomena of nonlinear wave propagation, including the presence and propagation of discontinuities and expansion waves. Such nonlinear systems can generate discontinuities ... 
Numerical Methods for Elliptic Variational Inequalities in Higher Dimensions
The main emphasis of this thesis is on developing and implementing linear and quadratic finite element methods for 3dimensional (3D) elliptic obstacle problems. The study consists of a priori and a posteriori error ... 
Numerical Simulation Of Converging Nonlinear Wavefronts
(20130124) 
Numerical Study Of Regularization Methods For Elliptic Cauchy Problems
(20110630)Cauchy problems for elliptic partial differential equations arise in many important applications, such as, cardiography, nondestructive testing, heat transfer, sonic boom produced by a maneuvering aerofoil, etc. Elliptic ... 
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 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, ... 
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 ), ... 
Optimal Control Of A Stochastic Hybrid System
(20121121) 
Orbit Model Analysis And Dynamic Filter Compensation For Onboard Autonomy
(20090304)Orbit of a spacecraft in three dimensional Inertial Reference Frame is in general represented by a standard set of six parameters like Keplerian Orbital Elements namely semimajor axis, eccentricity, inclination, ... 
Peristaltic Flows With Some Applications
(20071229)Peristalsis is a mechanism of pumping fluids in ducts when a progressive wave of area contraction or expansion propagates along the length of a distensible tube containing fluid. It induces in general propulsive and mixing ...

The PickNevanlinna Interpolation Problem : Complexanalytic Methods in Special Domains
(20180613)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 ... 
A Posteriori Error Analysis of Discontinuous Galerkin Methods for Elliptic Variational Inequalities
(20180215)The main emphasis of this thesis is to study a posteriori error analysis of discontinuous Galerkin (DG) methods for the elliptic variational inequalities. The DG methods have become very popular in the last two decades ...
