  • Cohomological detection of Algebraic cycles 
    Ravindra, G.V. (2009-08-31)
    The objective of this thesis is twofold. The first is to give simpler more unified treatment, for all the diverse examples of non-trivial nullhomologous cycles. Then this would allow to construct new examples of such ...
  • Aspects of Black holes in Anti-deSitter Space 
    Suneeta, Varadarajan (, 2009-08-31)
    Some aspects of black holes in Anti deSitter Space times are studied in this thesis. A semi classical analysis of black holes shows that they also radiate with a thermal spectrum. This together with the fact that black ...
  • Control and synthesis of open reactive systems 
    Madhusudan, P. (2009-08-28)
    This thesis studies the problem of automated synthesis of controllers and systems against formal specifications. The two central aims are to study these control problems for branching time specifications and to study them ...
  • Persistence in non-equilibrium systems: a study on spatial correlations 
    Manoj, G. (, 2009-08-28)
    Some aspects of coarsening and the associated notion of persistence in a few well-known non-equilibrium processes are studied in this thesis. This thesis consists of 5 chapters. Apart from the introduction chapter, 2nd ...
  • Neutrino masses, Large mixings and phenomenology 
    Balaji, K.R.S. (, 2009-08-27)
    This thesis concentrates on a few aspects of massive neutrino physics. The effects of matter on neutrino oscillations is described, which are a consequence of massive neutrinos. A short description of the electromagnetic ...
  • Towards a semiclassical theory for quantum hall skyrmions 
    Dutta Sreedhar Babu (2009-08-27)
    This thesis addresses the following questions and discusses the answers: i) What is the limit in which the classical approximation is exact?; ii) When does the theory itself become classical? (Not just the energetics, ...
  • Confined quantum systems: a study of ground state and collective excitations 
    Sinha, Subhasis (, 2009-08-26)
    This thesis is devoted to the study of ground state and collective properties of a class of mesoscopic systems - quantum confined systems. In quantum confined systems the particles (bosons and fermions) are artificially ...
  • Some problems in Homogenization 
    Rajesh, M. (, 2009-08-26)
    Some problems in the homogenization of partial differential equations are considered for this study. The process of obtaining the macroscopic or effective properties of materials having heterogeneities on a scale much ...
  • Duality transformation of non-abelian gauge theories 
    Majumdar, Pushan (2009-08-25)
    Duality transformation typically maps the strongly coupled region of one theory to the weakly coupled one of another, making it possible for one to investigate the strongly coupled region of a theory by a perturbative ...
  • Dynamics of Driven Dissipative Heisenberg Spins with Inertia 
    Das, Jayajit (2009-08-25)
    This thesis is a study of the interplay between inertia, dissipation and driving on the dynamics of many-body systems in d-dimensions. The simplest example of a many-body spin system possessing inertial dynamics is the ...
  • Aspects of D-brane Physics and quantum gravity 
    Sarkar, Tapobrata (2009-08-25)
    Some aspects of D-brane physics and quantum gravity are studied in this thesis. D-branes on Calabi-Yau manifolds from the point of view of gauged linear sigma models are studied. An appropriate set of boundary conditions, ...
  • EigenValue Problems in Shell Theory 
    Sabu, N. (2009-08-24)
    This thesis studies the justification of eigenvalue problems for classical lower dimensional models of linear elastic shells and rods. It is to show that the eigen solutions of the lower dimensional problem is the limit, ...
  • Studies in Quantization: Methods for constrained systems and semi-classical spectra of Many-Body Systems 
    Radhika, Vatsan (, 2009-08-24)
    In many cases while interacting many-body systems, the quantum treatment has to be through approximations. One such aspect is semi-classical approximation. These aspects of quantization in the context of simple examples ...
  • Problems in Algorithmic Number theory 
    Nagaraj, S. V. (2009-08-24)
    This thesis presents new results for four problems in the field of Algorithmic and Computational Number Theory. The first gives an improved analysis of algorithms for testing whether a given positive integer n is a perfect ...
  • Aspects of Black Hole Thermodynamics 
    Arundhati, Dasgupta (, 2009-08-20)
    Black holes are formed when stars with mass around few times the mass of our Sun or higher collapse under their own gravitational field. Black holes are solutions of Einstein's equation which relates space time to matter. ...
  • Counting complexity and computational group theory 
    Vinodchandran, N.V. (, 2009-08-19)
    The main contribution of this thesis is in proving upper bounds on the counting complexity of some computational problems that arise from group theory. It consists of two parts. The first part concentrates on studying the ...
  • Phenomenological consequences of Neutrino Oscillations 
    Mohan, Narayan (, 2009-08-19)
    This thesis makes a systematic analyses of the solar and the atmospheric neutrino problems in a single framework in which all the three flavors of neutrinos can mix with each other. The region which is allowed by solar ...
  • Models for concurrency: Local presentations for finite state distributed systems 
    Swarup Kumar, Mohalik (, 2009-08-19)
    It is aimed to study the models of concurrency in the context of finite state systems, in order to understand the nature of distributed computing, and to help the design and analysis of distributed systems. Process models ...
  • Aspects of gravitational scattering at Planckian energies 
    Saurya Das (2009-08-18)
    The standard Model is a gauge field theory based on the gauge group. As for the standard theory of elementary particle interactions, gravitation remains negligible at the highest of energies accessible to present day ...
  • Variational formulae for Fuchsian groups over families of Algebraic curves [UNM Th54] 
    Dakshini, Bhattacharyya (, 2009-08-18)
    This thesis contributes to the problem of understanding the uniformizing Fuchsian groups for a family of plane algebraic curves by determining explicit first variational formulae for the generators of the Fuchsian groups ...
