Computations in linear algebra: a new look at residue arithmetic.
The dissertation deals with error-free and approximate computations of some problems in linear algebra, with an emphasis on a modified residue arithmetic developed here. It is divided into five chapters:Chapter 1 The ... -
EPR study of the phase transitions in LIKSO4 and certain similar salts.
This thesis represents basically an attempt to investigate the low temperature phase transitions of LiKSO^ (LKS) through Electron Paramagnetic Resonance (EPR). There have been of course umpteen publications on the ... -
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 ... -
Study of the source-substrate geometry to achieve thickness uniformity of thin films
Despite the various technical skills that are available, the thickness uniformity cannot be made better than ±1% on a large number of substrates. In addition to the theoretical limitations, one has practical difficulties ... -
Theoretical studies on impurity models of mixed valent systems
In the first part of this thesis, consisting of the first 3 chapters, calculations of thermodynamic properties like susceptibility, magnetisation and specific heat, and of the single particle spectral density are discussed, ... -
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 ... -
Unified geometrical framework for gauge symmetries
The effort to discover a conceptual unity among various phenomena in the physical world is one of the major intellectual endeavours of the human mind. It is surprising that Nature apparently supports such an instinct, for, ... -
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 ...
