    • Groups defined by language theoretic classes 

      Al Kohli, Raad Sameer Al Sheikh (2024-06-11) - Thesis
      In this thesis we shall study classes of groups defined by formal languages. Our first main topic is the class of groups defined by having an ET0L co-word problem; i.e., the class of co-ET0L groups. We show this class is ...

    • Efficient methods for fitting nonlinear non-Gaussian state space models of wildlife population dynamics 

      Empacher, Fanny (2024-06-11) - Thesis
      State-space models (SSMs) are a popular and flexible framework for modelling time series due to their ability to separate changes in the underlying state of a system from the noisy observations made on these states. This ...

    • 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 ...
