Theoretical studies in micropolar and viscoelastic fluids
We record below a summary of the results of our investigations. The linear micropolar fluid is a viscous fluid with five additional coefficients of viscosity, apart from the usual Newtonian fluid. In its flow behaviour it ... -
Theoretical studies on some superconductors.
Superconductivity can be considered to be one of the most attractive branches of solid-state physics. This is especially true now, with the sensational discoveries of high transition-temperature superconductors. On the ... -
Three Dimensional Boundary Layer with suction and injection
Chapter I deals with the study of incompressible boundary layer over a yawed semi-infinite flat plate with suction or injection by modified Pohlhausen method. IN the first two parts, a comparison of three different velocity ... -

Total variation cutoff for random walks on some finite groups
This thesis studies mixing times for three random walk models. Specifically, these are random walks on the alternating group, the group of signed permutations and the complete monomial group. The details for the models are ... -
Toward Computationally Efficient Models for Near-infrared and Photoacoustic Tomographic Imaging
(2017-11-28)Near Infrared (NIR) and Photoacoustic (PA) Imaging are promising imaging modalities that provides functional information of the soft biological tissues in-vivo, with applica-tions in breast and brain tissue imaging. These ... -
Trace Estimate For The Determinant Operator And K- Homogeneous Operators
Let $\boldsymbol T=(T_1, \ldots , T_d)$ be a $d$- tuple of commuting operators on a Hilbert space $\mathcal H$. Assume that $\boldsymbol T$ is hyponormal, that is, $\big [\!\!\big [ \boldsymbol T^*, \boldsymbol T \big ]\!\! ... -
Unfolding Operators in Various Oscillatory Domains : Homogenization of Optimal Control Problems
(2018-06-13)In this thesis, we study homogenization of optimal control problems in various oscillatory domains. Specifically, we consider four types of domains given in Figure 1 below. Figure 1: Oscillating Domains The thesis is ... -
Unsteady laminar boundary layer studies through finite difference methods
This thesis embodies a study of some problems in unsteady laminar compressible and incompressible boundary layer theory. The thesis is divided into five chapters. Each chapter contains a brief survey of the literature relevant ... -
Vector Bundles Over Hypersurfaces Of Projective Varieties
(2014-06-02)In this thesis we study some questions related to vector bundles over hypersurfaces. More precisely, for hypersurfaces of dimension ≥ 2, we study the extension problem of vector bundles. We find some cohomological conditions ... -
Weighted Norm Inequalities for Weyl Multipliers and Hermite Pseudo-Multipliers
(2018-05-30)In this thesis we deal with two problems in harmonic analysis. In the first problem we discuss weighted norm inequalities for Weyl multipliers satisfying Mauceri’s condition. As an application, we prove certain multiplier ... -
Weights of highest weight modules over Kac-Moody algebras
In this dissertation, broadly, we treat the weight-sets of arbitrary highest weight modules (uniformly) over all general complex Kac-Moody Lie algebras $\mathfrak{g}$, achieving the below. We obtain a uniform, explicit, ... -
Wiener-hopf technique and allied methods in a class of scattering problems
This thesis is devoted to the study of a class of boundary value problems arising in the scattering of electromagnetic and acoustic waves by means of the Wiener–Hopf technique and related methods. The contents are organized ...
