  • Investigations into Quantum Compass Models in Two Dimensions [HBNI Th225] 
    Soumya Sur (The Institute of Mathematical Sciences, 2023)
    Quantum many-body systems with competing interactions are found to be potential candidates to host unconventionally ordered phases and fractionalized excitations. The exactly soluble Kitaev’s 2d spin model has incited ...
  • Investigations on the Kitaev Model and some of its generalisations[HBNI Th30] 
    Saptarshi Mandal (The Institute of Mathematical Sciences, 2012)
    This thesis studies a frustrated quantum spin 1/2 model on a hexagonal lattice [A] which was originally proposed and analysed by A. Kitaev. This model was introduced for possible implementation in the field of topological ...

  • The Kernelization complexity of some domination and covering problems [HBNI Th44] 
    Geevarghese Philip (The Institute of Mathematical Sciences, 2012)
    Polynomial-time preprocessing is a simple algorithmic strategy which has been widely employed in practice to tackle hard problems. The quantification and analysis of the efficiency of preprocessing algorithms are, in a ...
  • Kernels for the F-Deletion Problem[HBNI Th41] 
    Neeldhara Misra (The Institute of Mathematical Sciences, 2012)
    In this thesis, the parameterized framework is used for the design and analysis of algorithms for NP-complete problems. This amounts to studying the parameterized version of the classical decision version. Herein, the ...
  • Keynote address: High energy physics in 2014 and its future 
    Rajasekaran G. (Indian Academy of Sciences, Bangalore, 2016)
    After a brief history, we focus on the present status of HEP and its possible future. Ideas to ensure a healthy growth of HEP in India are discussed. This involves a few major experimental projects in fundamental physics. ...
  • KVL Sarma (1937-1997) - Obituary note 
    Rajasekaran G. (Indian Academy of Sciences, 1998)
  • L0-Types common to a Borel-De Siebenthal Discrete series and its associated holomorphic discrete series[HBNI Th60] 
    Pampa Paul (The Institute of Mathematical Sciences, 2013)
    In this thesis, to each Borel-de Siebenthal discrete series representation of G(0), the author would associate a holomorphic discrete series representation of K*(0). The main aim of the thesis is to compare the restrictions ...
  • Labelled free choice petri nets, finite product Automata, and Expressions[HBNI Th83] 
    Phawade Ramchandra Babasaheb (The Institute of Mathematical Sciences, 2014)
    Petri nets are a formal model of concurrent systems. They were first defined by Petri in his thesis [Pet62] and were presented at the IFIP 1962 congress in Munich [Pet63]. Nets are widely used in modelling various aspects ...
  • Large neutrino mixing angles for type-I see-saw mechanism in SO(100 GUT 
    Bipin.R.Desai.; Rajasekaran G.; Utpal Sarkar (arXiv, 2005)
    We consider the neutrino mixing angles in an SO(10) GUT with the usual Higgs structure in which neutrino masses are explained by the type-I see-saw mechanism. The Dirac-neutrino Yukawa matrix then has a structure similar ...
