Numerical studies of some laminar boundry layer flows using finite difference methods
This thesis presents some investigations on certain problems in laminar incompressible and compressible boundary layers using finite?difference methods. It consists of an introductory chapter and three main chapters. Each ... -
Mathematical theory of the propagation of multidimensional shock and nonlinear waves
This thesis embodies the results of our investigation on a mathematical discussion of hyperbolic nonlinear waves under the high frequency approximation. It is divided into four chapters, of which Chapter I is the introduction ... -
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 ... -
ome boundary value problems for helmholtz equation arising in diffraction theory
In recent years, the problem of wave diffraction by semi?infinite obstacles with edges, in particular half plane and strip under mixed boundary conditions (Dirichlet on the top and Neumann condition on the bottom surface) ... -
Convergence of state distributions in multi-type Bellman-Harris and Crump Mode-Jagers branching processes
Athreya and Kaplan proved recently that the age distribution in a one?type supercritical Bellman–Harris process converges with probability one to a deterministic distribution, assuming either a j log j hypothesis on the ... -
Numerical studies of rotating laminar boundary-layer flows
This thesis presents numerical studies on certain problems in steady and unsteady laminar boundary?layer flows involving rotation of either the fluid or the body. It consists of four chapters: the first is introductory, ... -
Studies on graph grammars : comparison of various models and applications to graph theory
In this short chapter we shall raise a few questions whose answers could throw further light on the theory of graph grammars. When the notion of contextual condition was introduced by Rosenfeld, the grammars were constructed ... -

On some structural problems in the theory of infinite-dimensional Lie (super)algebras
In this thesis, we examine two facets of infinite-dimensional Lie algebras. The first part focuses on the classification of $\pi$-systems in rank 2 Kac-Moody Lie algebras. In one of his seminal works, Dynkin classified the ... -
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 ... -
Analysis of some unsteady laminar boundary - layer flows using numerical methods
This thesis presents the analysis of the numerical investigations of some unsteady laminar incompressible boundary?layer flow problems. It consists of five chapters. The first chapter deals with a general introduction to ... -
Mangnetohydrodynamic flow and diffusion in channels or pipes with some physiological applications

Optimal control and differential games in a Hilbert space
In this thesis, we study some aspects of optimal control and differential game problems in an infinite-dimensional Hilbert space. We mainly discuss the dynamic programming and viscosity solution approach to these problems. ...
