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 ... -
Kinematical conservation laws and applications
Study of wave motion is important in the field of fluid mechanics. The equations governing the motion of an inviscid compressible fluid form a hyperbolic system of quasi-linear equations and hence give rise to nonlinear ... -
Grushin Multipliers and Toeplitz Operators
This work investigates advanced concepts in functional analysis and partial differential equations, focusing on Sobolev spaces and their weighted variants. The study explores properties of functions in Lp(Rn+1)L^p(\mathb ... -
A Study and development of numerical techniques for the solution of integral equations
We have shown that given any function f(x), there exists a unique f?(x), as defined by the relation (2.1), which exactly coincides with f(x) at the points jh. By using the package MATHEMATICA, we can choose a k, such that ... -
Benard-Marangoni convection and instability in a layered fluid system
Buoyancy-driven instability has been well established since the pioneering work of Rayleigh, who showed that convection, called Bénard convection, occurs only when the Rayleigh number, which is a ratio of buoyancy force ... -
Field theories in nanocommutative spaces
The recent interest in noncommutative spaces has its roots in the study of quantum gravity and string theory. At length scales close to the Planck scale, the usual notion of continuous spacetime is expected to break down ... -
Some flow problems in noncoaxial rotating systems
We live in an atmosphere of air and water which involve rotation to a greater or lesser extent. The atmosphere and the oceans rotate as a whole with the earth and move over its surface as winds and ocean currents which ... -
Electromagnetic waves in plasmas
This thesis embodies the investigations on the electromagnetic waves in plasmas. The investigations fall under two general headings, namely, wave propagation in plasmas in the presence of the Coriolis force (Part I) and ... -
numerical studies of laminar compressible boundary layer flows with heat and mass transfer
This thesis presents a numerical study of some laminar compressible boundary-layer flows with heat and mass transfer. It consists of five chapters: the first is an introductory one, the remaining four are concerned with ... -
Numerical studies of unsteady double diffusive mixed convective boundary_layer flows
In the present thesis, some problems in unsteady mixed convective boundary-layer flows with double diffusion have been numerically investigated. It consists of five chapters-the first of which is a general introduction to ... -
Numerical investigations of unsteady incompressible boundary - layer flows
This thesis presents a numerical study of some problems in unsteady, laminar incompressible boundary-layer theory. It is divided into five chapters, the first being a general introduction to boundary-layer theory with ... -
Swiriling flows between rotating coaxial and non-coaxial disks
In this thesis an attempt is made to study some steady and unsteady flow problems due to a single rotating disk and two disks rotating coaxially or non-coaxially in different fluid media in a variety of interesting situations. ... -
Numerical studies of some problems in mixed convection boundary layer flows
This thesis embodies the results of our investigations on some problems in mixed convection boundary-layer flows. It is divided into four chapters, the first being a general introduction to boundary-layer theory, mixed ...
