  • Brusselator as a Reaction-Diffusion system 
    Rajeev Singh (, 2009-09-24)
    In this work the Brusselator model is studied, which is a minimal mathematical model, for chemical oscillations. The mean field analysis for the model and the traditional way of adding the effect of diffusion is reviewed. ...
  • Cosmological Perturbation Theory 
    Sabapathy, KrishnaKumar (2009-09-24)
    This study is a review of Cosmological perturbation theory. The theory aims to model the physical universe by perturbing about a background Friedmann-Robertson-Walker cosmological model. Two approaches are highlighted, ...

    Kurur, Piyush P. (2009-09-23)
    This thesis studies the Graph Isomorphism and problems that arise in Galois theory. It is targeted to use structural properties of permutation groups together with other algebraic techniques to prove complexity upper ...
  • Studies in Loop Quantization of cosmological models[HBNI Th9] 
    Kinjal Banerjee (The Institute of Mathematical Sciences, 2009)
    This thesis presents some studies on the Loop Quantization of cosmological models. The effect of loop quantization of FRW cosmology in the context of effective equations and WKB approximation are studied in the first ...
  • Complexity Theoretic aspects of Rank Rigidity and circuit evaluation[HBNI Th8] 
    Jayalal Sarma, M. N. (The Institute of Mathematical Sciences, 2009)
    This thesis studies some combinatorial, topological and linear algebraic parameters associated with Boolean and arithmetic circuits. It is divided into two parts, the first describes a study of combinations of graph ...
  • Phenomenology of a B Meson and CP violation[HBNI Th7] 
    Sharma, Chandradew (The Institute of Mathematical Sciences, 2009)
    The New Physics, the Physics beyond the Standard Model, shows that New Physics which affects B decays with any topological amplitude can be absorbed by redefinitions of the SM amplitudes. This thesis studies the B → K∗ρ ...
  • Exact Algorithms for Optimization and parameterized versions of some graph theoretic problems[HBNI Th6] 
    Saket Saurabh (The Institute of Mathematical Sciences, 2009)
    The class of NP-hard combinatorial optimization problems, need to be solved exactly for various applications in theory and practice, brings the need for exact algorithms. Parameterized complexity is an exact algorithmic ...
  • Classifying certain algebraic problems using Logspace counting classes[HBNI Th5] 
    Vijayaraghavan, T. C. (The Institute of Mathematical Sciences, 2009)
    In this thesis the results showing a finer classification of the complexity of several algebraic problems that have efficient polynomial time algorithms are obtained. The problems based on Group theory and Linear Algebra ...
  • Studies in SU(2) Savvidy model of QCD[HBNI Th4] 
    Alok Kumar (The Institute of Mathematical Sciences, 2009)
    Quantum Chromo Dynamics is accepted as the theory of strong interaction of quarks and gluons. It is a gauge theory with the gauge group as SU(3)C1 the unbroken color group. In this thesis the author examines the ground ...
  • Some explicit minimal graded free resolutions[HBNI Th2] 
    Aaloka, Kanhere (The Institute of Mathematical Sciences, 2009)
    This thesis has three parts. In the first part an irreducible curve C in P^2 is considered. The Veronese map is used for mapping it to P^5 and the resolutions are computed. In the second part, looking into two distinct ...
  • Acyclic edge colouring: Bounds and algorithms[HBNI Th3] 
    Rahul Muthu (The Institute of Mathematical Sciences, 2009)
    An acyclic edge colouring of a graph is an assignment of colours to its edges in such a way that incident edges get distinct colours, and the edges of any cycle use atleast three distinct colours. The latter condition is ...
  • Planar Algebra of the Subgroup-Subfactor[HBNI Th1] 
    Ved Prakash, Gupta (The Institute of Mathematical Sciences, 2009)
    An identification between the planar algebra of the subgroup-subfactor R x H subset of R x G is given and the G-invariant planar subalgebra of the planar algebra of the bipartite graph *n (the graph with 1 odd and n even ...
  • Explicit integral Galois Module structure for low degree abelian extensions 
    Manisha, V. Kulkarni (, 2009-09-14)
    'Let M be a finite abelian extension of of Q. Then the ring of integers OM of M is a free, rank one module over the associated order AM/Q'. There is no method for constructing a Z(G) basis for OM when OM is free over Z(G). ...
  • Asymptotic behaviour of some Optimal Control Problems 
    Muthukumar, T. (, 2009-09-14)
    The theory of homogenization of partial differential equations is a concept that deals with the study of the macroscopic behaviour of a composite medium through its microscopic properties. The aim of this thesis is to ...
  • 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 ...
