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 ... -
Small amplitude phenomena in conducting fluids and transport properties of plasmas

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. ... -
A Neumerica study of laminar compressible boundary-layer problems
This thesis presents some investigations on certain problems in laminar compressible boundary-layer theory. It consists of an introductory chapter and three main chapters. A brief survey of the literature relevant to the ... -
Phase transition at critically, poisson convergence of isolated vertices and connectivity in random connection models
This work has two parts. The first part contains the study of phase transition and percolation at criticality for three random graph models on the plane, viz., the homogeneous and inhomogeneous enhanced random connection ... -
Nonlinear wave propagation in muln dimensions
This thesis consists of four chapters including a chapter on general introduction and deals with some problems in nonlinear wave propagation in multi-dimensions. The problems are: nonlinear wave propagation in a two-dimensional ... -
Iterative and direct P;Adic algorithms for exact solution of numerical problems
In this chapter, we have described an O(n³), 2 < P < 3 algorithm for inverting integer matrices using p-adic computations. Some of the important aspects of this method are: (a) Absence of any convergence problems – the ...
