  • Constacyclic codes over finite commutative chain rings 
    Sidana, Tania; Sharma, Anuradha (Advisor) (IIIT-Delhi, 2020-07)
    Constructing codes that are easy to encode and decode, can detect and correct many errors and have a sufficiently large number of codewords is the primary aim of coding theory. Several metrics (e.g. Hamming metric, Lee ...
  • Multi-twisted codes over finite fields and their generalizations 
    Chauhan, Varsha; Sharma, Anuradha (Advisor) (IIIT-Delhi, 2021-01)
    Nowadays error-correcting codes are widely used in communication systems, returning pictures from deep space, designing registration numbers, and storage of data in memory systems. An important family of error-correcting ...
  • Spatio-temporal linear stability of viscoelastic saffman-taylor flows 
    Ghosh, Dipa; Sircar, Sarthok (advisor) (IIIT-Delhi, 2024-03)
    This thesis is about an analytical study of viscoelastic fingering that solves the problem of predicting the finger width when a Newtonian fluid (with negligible viscosity) drives a non-Newtonian (power-law) fluid. The ...
  • Spatiotemporal linear stability of viscoelastic free shear flows 
    Bansal, Diksha; Sircar, Sarthok (Advisor) (IIIT-Delhi, 2021-03)
    In this thesis, we have explored the temporal and spatiotemporal stability analyses offree shear, viscoelastic flows in the limit of low to moderate Reynolds number (Re) and Weissenberg number (We). The description of the ...
  • Unimodular polynomial matrices and partial linear transformations over finite fields 
    Arora, Akansha; Ram, Samrith (Advisor) (IIIT-Delhi, 2022-11)
    This thesis consists of some interesting combinatorial problems on matrix poly- nomials over finite fields. Using results from control theory, we give a proof of a result of Lieb, Jordan and Helmke (2016) which solves the ...
