  • D-Branes on Landau-Ginsberg orbifolds and Calabi-Yau spaces. 
    Ezhuthachan, Bobby Vinod Kr. (, 2009-09-14)
    In this thesis the author had tried to identify the objects that correspond, at large volume to the fractional 2-branes in C^n / ZN orbifolds. The fractional two-branes have a fractional first Chern class and also have ...
  • Studies in Loop quantum Cosmology 
    Hossain, Golam Mortuza (2009-09-11)
    The standard model of cosmology is based on Einstein's relativistic theory of gravity, together with an implementation of the cosmological principle. It is formulated using the Friedmann-Robertson Walker(FRW) solution of ...
  • Aspects of Particle Emission from Black Holes 
    Soumen, Basak (, 2009-09-11)
    Using the analogy between a shrinking fluid vortex (drain bath tub) modelled as a (2+1)-dimensional fluid flow with a sink at the origin, and a rotating black hole with an ergosphere, it is shown that a scalar sound wave ...
  • Aspects of noncommutativity in Field and String theory and Closed String Tachyon Condensation 
    Swarnendu, Sarkar (, 2009-09-11)
    This thesis studies two problems; The first part of the thesis analyses some of the aspects of noncommutativity in field and string theory; The mixing of the ultraviolet and the infrared sectors in noncommutative field ...
  • Reasoning about distributed message passing systems 
    Meenakshi, B. (, 2009-09-10)
    This thesis is concerned with the use of formal methods towards automatic verification of distributed message passing systems with a fixed finite number of agents. Main concentration is on developing logics to reason about ...
  • Topology of Toric Varieties 
    Uma, V. (, 2009-09-09)
    This thesis is devoted to a study of the cohomology and K-theory of complex toric bundles and the fundamental group of real toric varieties. Since the discovery of toric varieties in the early 1970's, the subject has ...
  • Foundations of Security Protocol Analysis 
    Suresh, S. P. (2009-09-09)
    One of the central problems in the automatic verification of security protocols is that of verifying whether a given protocol leaks secrets or not. It identifies syntactic subclasses of protocols for which the secrecy ...
  • Quantum spin liquids and connections with nonlinear sigma models 
    Naveen, Surendran (, 2009-09-08)
    The low energy properties of many strongly correlated electronic systems can be described by an effective theory in terms of just spin degrees of freedom. One of the simplest interacting model, Heisenberg model has been ...
  • Theoretical study of excitations in interacting Bose and Fermi systems 
    Ghosh, Tarun Kanti (2009-09-04)
    This thesis is devoted to theoretical study of various aspects of low energy collective excitations in a trapped interacting alkali-metal atomic gases (Bose and Fermi) and of fractional quantum hall systems. An equation ...
  • Geometry of Moving space curves associated with integrable equations: Connections and applications 
    Murugesh, S. (, 2009-09-03)
    An unified approach to study possible connections between the geometry of moving space curves in three dimensional space and integrable nonlinear evolution equations in (1+1) dimensions, has been formulated. This unified ...
  • Aspects of Matrix Models 
    Subrata Bal (, 2009-09-02)
    The matrix model is an impressive candidate for M-theory (Non perturbative string theory). This thesis investigates the two important aspects of the Physics of Matrix Model, finite temperature matrix model and Fuzzy ...
  • Succinct data structures 
    Srinivasa Rao, S. (2009-09-01)
    This thesis aims to develop space efficient structures for some of the most fundamental problems in the area of data structures. The design of data structures that use almost optimal space while supporting the operations ...
  • 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)
