    • Rearrangement groups of connected spaces 

      Khalid, Nayab (University of St Andrews, 2020-07-28) - Thesis
      We develop a combinatorial framework that assists in finding natural infinite “geometric” presentations for a large subclass of rearrangement groups of fractals – defined by Belk and Forrest, namely rearrangement groups ...
    • Internal interannual variability in the extra-tropical stratosphere 

      Hatfield, Luke Anthony (University of St Andrews, 2021-11-30) - Thesis
      We investigate persistent low-frequency variability of the stratospheric winter polar vortex in a rotating spherical shallow-water model under the action of topographic wave-forcing and radiative cooling to a simple ...
    • Expanding the use of spatial models in statistical ecology 

      Seaton, Andrew Ernest (University of St Andrews, 2022-06-14) - Thesis
      This thesis is focused on expanding the use of spatial modelling approaches for applications in ecology. Spatial ecology is about understanding the processes that give rise to spatial patterns in ecological data. In addition ...
    • Modern computational methods for finitely presented monoids 

      Tsalakou, Maria (2024-06-11) - Thesis
      In this thesis we are mainly interested in the development of practical algorithms for semigroups and monoids defined by finite presentations. Although in general nearly every problem about finitely presented semigroups ...
    • Combinatorial algorithms in semigroups 

      Smith, Finlay Laughlan (University of St Andrews, 2022-06-14) - Thesis
      Computational semigroup theory is concerned with developing and implementing algorithms for determining properties of semigroups. The problems in computational semigroup theory can often be divided into sub-problems in ...
